Natural satellites of the planets of the solar system. Which planet in the solar system has the fewest moons? Which planet has 16 satellites

Satellites are small bodies that orbit planets. In the solar system, two planets (Mercury and Venus) have no satellites, the Earth has one, and Mars has two. A large number of satellites are attracted by the magnetic field of Neptune (13 satellites), Uranus (27 satellites), Saturn (60 satellites). But Jupiter has the largest number of satellites. There are 63 of them! Now you know which planet has more satellites in the solar system.

In addition to such a huge number of satellites, Jupiter also has a system of rings. The first 4 satellites of Jupiter, the largest, were discovered by Galileo at the beginning of the 17th century. He gave them the names Europa, Ganymede, Io, Callisto (names of mythical heroes). With the development of telescopic technology, the remaining satellites began to be discovered; in the 70s of the last century, 13 of them were discovered. At the beginning of the third millennium, 47 more satellites of Jupiter were discovered. They are quite small, their radius reaches 4 km. Who knows how many more satellites of planets will be discovered over time, when the scientific and technological progress of mankind...

Which planet has the most satellites?

The planet Jupiter has the largest number of satellites among the planets of the Solar System - as many as 63. In addition to them, this planet also boasts a system of rings. The first 4 satellites were discovered back in the Middle Ages in the 17th century using a telescope, and the last (most of them) were discovered at the end of the 20th century using spacecraft. The size of most of them is not too large - only 2 to 4 kilometers in diameter. Saturn has slightly fewer satellites - 60. But one of its satellites, Titan, is the second largest in the Solar System and has a diameter of 5100 km.

The third largest number of satellites is Uranus. He has 27 of them. And planets such as Venus and Mercury have no satellites at all. 5-11-2010

At Jupiter...

Mercury has no satellites.

Venus also has no satellites

The Earth has one satellite: the Moon
The Moon is the only natural satellite of the Earth. It is the second brightest object in the earth's sky after the Sun and the fifth largest natural satellite in the solar system. It is also the first (and as of 2009, the only) extraterrestrial object of natural origin visited by humans. The average distance between the centers of the Earth and the Moon is 384,467 km.

The planet Mars has two satellites: Phobos (Greek - fear) and Deimos (Greek - horror).
Both satellites rotate around their axes with the same period as around Mars, therefore they are always turned to the planet with the same side. The tidal influence of Mars gradually slows down the movement of Phobos, and will eventually lead to the fall of the satellite onto Mars. On the contrary, Deimos is moving away from Mars.

Jupiter has 63 moons
The moons of Jupiter are the natural satellites of the planet Jupiter. To date, scientists know 63...

The central star of our system, around which all the planets pass in different orbits, is called the Sun. Its age is about 5 billion years. It is a yellow dwarf, so the size of the star is small. Its thermonuclear reactions are not consumed very quickly. The solar system has reached approximately the halfway point of its life cycle. After 5 billion years, the balance of gravitational forces will be disrupted, the star will increase in size and gradually warm up. Nuclear fusion converts all of the sun's hydrogen into helium. At this point, the size of the star will be three times larger. Ultimately, the star will cool down and shrink. Today the Sun consists almost entirely of hydrogen (90%) and some helium (10%).

Today, the satellites of the Sun are 8 planets, around which other celestial bodies revolve, several dozen comets, as well as a huge number of asteroids. All these objects move in their orbit. If you add up the mass of all the solar satellites, it turns out that they are 1000 times lighter than their star....

That's a moot point. Each country chooses different cars for taxi work. Basically, the selection of cars is based on price. The technical characteristics of the car are very important. Now that there is quality car service, Why do all the planets look different? The reason the planets appear different to us is because each one is made of different substances. Even though they all revolve around the Sun and are part of the same solar system, their composition differs. Very little is known about what the planets are made of, and this is one of those questions that people hope to get answered with the help of space research that has been carried out and that is being planned. It turns out that there are so many different bodies in the Galaxy and they are all divided into types and classes. For example, more than once you hear that on such and such a planet or star... and so on. What is the difference between a star and a planet? The difference between them is quite large, although not noticeable at first glance. To make it more clear, imagine our Sun and Earth. The sun is a real star. But the Earth For those who decide to learn any foreign language, you should pay attention to the fact that there are subjective and objective assessments of practical actions. Subjective ones talk about the closeness of the new language to the native one, and objective ones talk about the number of rules that describe the language being studied. The fewer there are, the easier it is to learn. There are the following Levels of complexity of languages: - first - these are the easiest (English, French, Italian, Spanish, German). - second - medium difficulty Why do planets revolve around the Sun? Have you ever spun a ball tied to a string? Then you know that while the ball is spinning, it is pulling on the string. The ball will pull on the string as long as its rotational motion continues. The planets move just like your ball. Only they have much more mass. And besides, the planets revolve around the Sun. But where is the rope that holds them? In fact, there is no string. Exists

Where does your interest in astronomy begin? From school lessons? From an excursion to the observatory? Personally, for me it all started with books by Isaac Asimov, which was called quite banally: “David Starr and the Moons of Jupiter.” The story about the giant planet and its many satellites was so fascinating that the next time I went to the library not for science fiction, but for books on astronomy. Moreover, I really wanted to check whether I wrote the truth in the story, and in reality?

Moons of Jupiter

Our Solar System is a completely unique phenomenon. The main thing that I have understood over the years of being passionate about astronomy is that not a single question can be answered unambiguously. So with the number of satellites everything is very difficult. In terms of the number of planets revolving around the planet, the absolute leader will, of course, be Jupiter.

In total, this gas giant, named after the Roman god of thunder, 69 known to modern science satellites. Some of them - Callisto, And about, Ganymede And Europe- so large that they can be seen even with not very powerful binoculars. I first discovered them Galileo V 1610.

Jupiter is a very “greedy” planet (as, by the way, is the deity who shared her name with it). Almost half of his satellites have retrograde orbit. They can be difficult to detect because they move in the opposite direction and therefore their trajectory is more difficult to calculate. The reason for this strange movement is simple: the planets were stolen by a giant planet from less massive neighbors. These “prisoners” include:

• Paphise;
• Euporia;
• Gelike;
• Telksinoe;
• Harpalike;
• Evante;
• Tione;
• Jocasta;
• Calais;
• Ananke;
• Germippe;
• and about two dozen more planetoids of different sizes and shapes.

And how many small satellites can this gas giant have? not yet discovered astronomers! For example, a tiny 4-kilometer Diya was discovered through a telescope, but was soon lost, and its existence was confirmed only 12 years later!

Saturn is the leader in the number of small satellites

If we consider which planet has the most satellites, approaching this term literally - as a cosmic object revolving around a planet, then Jupiter will have to make room. The palm will be snatched from him Saturn, "Lord of the Rings" Solar System.

He has only officially recognized companions 62 , of which the largest, spherical in shape, are Rhea, Diona, ice balls Enceladus And Mimas, Tethys, consisting of water ice and rock. And, of course, the giant Titanium, the second largest after Ganymede. Its size is more than 5 thousand kilometers, and its mass is so great that it is capable of maintaining an atmosphere (and it is one and a half times denser than the earth’s).

And besides this, they revolve around Saturn three large rings, consisting, in addition to frozen gas, of asteroids of different sizes. The number of only the largest ones is estimated to be several hundred thousand!

Natural satellites are relatively small cosmic bodies that orbit larger “host” planets. In part, an entire science is dedicated to them - planetology.

In the 70s, astronomers assumed that Mercury had several celestial bodies dependent on it, as they detected ultraviolet radiation around it. It later turned out that the light belonged to a distant star.

Modern equipment allows us to study the planet closest to the Sun in more detail. Today, all planetary scientists in unison insist that it has no satellites.

Moons of the planet Venus

Venus is called Earth-like because they have similar compositions. But if we talk about natural space objects, then the planet named after the goddess of love is close to Mercury. These two planets in the solar system are unique in that they are completely alone.

Astrologers believe that Venus could have previously seen these, but to date not a single one has been discovered.

How many natural satellites does the Earth have?

Our native Earth has many satellites, but only one natural one, which every person knows about from infancy - this is the Moon.

The size of the Moon is more than a quarter of the diameter of the Earth and is 3475 km. It is the only celestial body with such large dimensions relative to the “host”.

Surprisingly, its mass is small - 7.35 × 10²² kg, which indicates low density. Multiple craters on the surface are visible from Earth even without any special devices.

What moons does Mars have?

Mars is a fairly small planet that is sometimes called red because of its scarlet hue. It is given by iron oxide, which is part of its composition. Today, Mars boasts two natural celestial objects.

Both moons, Deimos and Phobos, were discovered by Asaph Hall in 1877. They are the smallest and darkest objects in our comic system.

Deimos is translated as the ancient Greek god who spreads panic and terror. Based on observations, it is gradually moving away from Mars. Phobos, bearing the name of the god who brings fear and chaos, is the only satellite that is so close to the “master” (at a distance of 6000 km).

The surfaces of Phobos and Deimos are abundantly covered with craters, dust and various loose rocks.

Moons of Jupiter

Today, the giant Jupiter has 67 satellites - more than other planets. The largest of them are considered the achievement of Galileo Galilei, as they were discovered by him in 1610.

Among the celestial bodies orbiting Jupiter, it is worth noting:

• Adrasteus, with a diameter of 250 × 147 × 129 km and a mass of ~3.7 × 1016 kg;
• Metis - dimensions 60×40×35 km, weight ~2·1015 kg;
• Thebe, with a scale of 116×99×85 and a mass of ~4.4×1017 kg;
• Amalthea - 250×148×127 km, 2·1018 kg;
• Io with a weight of 9 1022 kg at 3660 × 3639 × 3630 km;
• Ganymede, which with a mass of 1.5·1023 kg had a diameter of 5263 km;
• Europe, occupying 3120 km and weighing 5·1022 kg;
• Callisto, with a diameter of 4820 km and a mass of 1·1023 kg.

The first satellites were discovered in 1610, some from the 70s to the 90s, then in 2000, 2002, 2003. The last of them were discovered in 2012.

Saturn and its moons

62 satellites have been found, of which 53 have names. Most of them consist of ice and rocks, characterized by a reflective feature.

The largest space objects of Saturn:

How many moons does Uranus have?

At the moment, Uranus has 27 natural celestial bodies. They are named after characters from famous works authored by Alexander Pope and William Shakespeare.

Names and list by quantity with description:

Moons of Neptune

The planet, whose name is similar to the name of the great god of the seas, was discovered in 1846. She was the first to be found using mathematical calculations, and not through observations. Gradually, new satellites were discovered until they counted 14.

List

Neptune's moons are named after nymphs and various sea deities from Greek mythology.

The beautiful Nereid was discovered in 1949 by Gerard Kuiper. Proteus is a non-spherical cosmic body and is studied in detail by planetary scientists.

Giant Triton is the iciest object in the solar system with a temperature of -240°C, and is also the only satellite that rotates around itself in the direction opposite to the rotation of the “master”.

Almost all of Neptune's satellites have craters and volcanoes on their surface - both fire and ice. They spew from their depths mixtures of methane, dust, liquid nitrogen and other substances. Therefore, a person will not be able to stay on them without special protection.

What are “planetary satellites” and how many are there in the solar system?

Satellites are cosmic bodies that are smaller in size than the “host” planets and rotate in the orbits of the latter. The question of the origin of satellites is still open and is one of the key ones in modern planetology.

Today, 179 natural space objects are known, which are distributed as follows:

• Venus and Mercury – 0;
• Earth – 1;
• Mars – 2;
• Pluto – 5;
• Neptune – 14;
• Uranium – 27;
• Saturn – 63;
• Jupiter - 67.

Technology improves every year, finding more celestial bodies. Perhaps new satellites will be discovered soon. We can only wait, constantly checking the news.

The largest satellite in the solar system

Ganymede, a satellite of the giant Jupiter, is considered the largest in our solar system. Its diameter, according to scientists, is 5263 km. The next largest is Titan with a size of 5150 km - the “moon” of Saturn. The top three is closed by Callisto, the “neighbor” of Ganymede, with whom they share one “master”. Its scale is 4800 km.

Why do planets need satellites?

Planetologists have always asked the question “Why are satellites needed?” or “What effect do they have on the planets?” Based on observations and calculations, some conclusions can be drawn.

Natural satellites play an important role for the “hosts”. They create a certain climate on the planet. No less important is the fact that they serve as protection against asteroids, comets, and other dangerous celestial bodies.

Despite such a significant impact, satellites are still not necessary for the planet. Even without their presence, life can form and sustain on it. This conclusion was reached by the American scientist Jack Lissauer from the NASA Space Science Center.

To the question: Which planet in the solar system has the most satellites? given by the author Sock the best answer is Maybe I’m wrong, but at the moment the planet Earth has the most satellites. Only these satellites are artificial (and the question didn’t say which ones). There are several hundred of them.

Satellites of the planets
Mercury and Venus have no satellites. The remaining planets, with the exception of the Earth, have satellites immeasurably smaller than their planets. The Earth has only one natural satellite - the Moon, but it is unusually large compared to itself. The Moon is only 4 times smaller in diameter than the Earth. The largest planet, Jupiter, has the most satellites - 12. The next most massive planet, Saturn, has 10 of them, and the last one was discovered only in 1966. Uranus has 5 satellites, Neptune and Mars have 2 each. The largest of the satellites are Titan (a satellite of Saturn) and Ganymede (the third satellite of Jupiter). They are 1.5 times the diameter of the Moon and slightly larger than Mercury. Titan is the only moon to have an atmosphere (made of methane).
All satellites for which rotation has been established, including the Moon, are always turned to their planet with the same side. Therefore, their stellar rotation periods are equal to their periods of revolution around their planets. As a result, the far side of its satellites cannot be seen from any planet. In relation to the Sun, the period of rotation of satellites around the axis is longer than in relation to the stars, since during the revolution of the satellite the planet along with it will travel some more arc along its circumsolar orbit.
A sidereal month is the period of the Moon's revolution around the Earth relative to the stars; A synodic month is the period of revolution of the Moon around the Earth relative to the Sun. A synodic month is the period of time between equal phases of the Moon. The sidereal month is 27.3 days, and the synodic month is 29.5 days.
The point of the elliptical lunar orbit closest to Earth is called perigee, and the most distant point is called apogee.
The moon is visible to us as a narrow crescent, the rest of its disk also glows slightly. This phenomenon is called ashen light and is explained by the fact that the Earth illuminates the night side of the Moon with reflected sunlight.
It is easy to understand that the phases of the Earth and the Moon are mutually opposite. When the Moon is almost full, the Earth is visible from the Moon as a narrow crescent.
Returning to the satellites of the planets, we note that the four largest satellites of Jupiter can sometimes be seen even with prism binoculars. Through a telescope, in a few hours you can see how the satellites move noticeably, sometimes passing between Jupiter and Earth, and sometimes going behind Jupiter’s body or into its shadow, into an eclipse. Observing these eclipses of satellites, Roemer in the 17th century. discovered that the speed of propagation of light is finite, and established its value.
Many of the planets' satellites are interesting because of their motion. The moons of Mars are very small. The largest of them is Phobos. It has a diameter of 16 km and is located from the surface of Mars at a distance less than the diameter of the planet. Phobos orbits Mars three times faster than the planet itself rotates on its axis. Therefore, it rises twice a day in the west and twice completely changes all phases, sweeping across the sky.
The distant moons of Jupiter and Saturn are very small, and some of them point in the direction opposite to the rotation of the planet itself.
All 5 satellites of Uranus rotate in the opposite direction, and the planes of their orbits, like the equator of the planet, are almost perpendicular to the plane of Uranus’s orbit.
