Test for small bodies of the solar system. Examination on the topic: "Solar System". Ministry of Common and Vocational Education

Reshebnik on astronomy 11 class on Lesson №16 (Workbook) - Small Body Solar System

1. Finish proposals.

Dwarf planets are a separate class of celestial objects.
Dwarf planets consider objects rotating around the stars that are not satellites.

2. Dwarf planets are (needed to emphasize): Pluto, Cerer, Charon, Vesta, Sedna.

3. Fill in the table: characterize the distinctive features of small bodies of the solar system.

4. Finish proposals.

Option 1.

The balance of the meteorite body, which did not burn in the earth's atmosphere and falling on the surface of the Earth, is called a meteorite.

The sizes of the comet can exceed millions of kilometers.

The core comet consists of cosmic dust, ice and frozen volatile connections.

Meteoric bodies break into the atmosphere of land with speeds of 7 km / s (burn in the atmosphere) and 20-30 km / s (do not burn).

The radiant is a small section of the sky, from which the visible paths of individual meteors of the meteororal flow are diverged.

Large asteroids have their own names, for example: Pallada, Junon, Vesta, Astrea, Heba, Irida, Flora, Metyda, Gigai, Parfenop, etc.

Option 2.

A very bright meteor, visible on Earth as a fireball flying across the sky is a bar.

Comet head reach the size of the sun.

The tail of the comet consists of discharged gas and the smallest particles.

Meteoric bodies flying into the atmosphere of the Earth are shone, evaporate and completely burned at altitudes 60-80 km, meteorite bodies can be laid with the surface.

The solid fragments of the comet are gradually distributed in the orbit of comets in the form of a cloud stretched along orbit.

The orbits of most asteroids in the solar system are located between the orbits of Jupiter and Mars in the belt of asteroids.

5. Is there a fundamental difference in the physical nature of small asteroids and major meteorites? Answer argue.

The asteroid becomes a meteorite only when it gets into the atmosphere of the Earth.

6. The figure shows the scheme of the Meeting of Earth with a meteoric flow. Analyze the drawing and answer questions.

What is the origin of the meteororal stream (Roy meteor particles)?

The meteoric flow is formed during the decay of the cometary nuclei.

What depends on the period of circulation of the meteor flow around the sun?

From the period of referring to the comet-kindness, from the perturbation of the planets, the rate of emission.

In which case on Earth there will be the greatest number of meteors (meteor, or starry, rain)?

When the Earth crosses the main mass of the meteorite moay particles.

What principle is the names of meteorl flows? Name some of them.

According to the constellation where the radiant is located.

7. Picture a comet structure. Specify the following elements: kernel, head, tail.

8. * What energy is released when the meteorite is impaired with a mass M \u003d 50 kg, having a speed at the surface of the Earth V \u003d 2 km / s?

9. What is the big half-one of the orbit of the Komet Gallet, if the period of its circulation T \u003d 76 years?

10. Calculate the approximate width of the Perseid meteor flux in kilometers, knowing that it is observed from July 16 to August 22.
