Reshebnik in astronomy grade 11 for lesson number 16 (workbook) - Small bodies of the solar system

| Characteristics | asteroids | Comets | meteorites |
| View in the sky | star-like object | diffuse object | "Shooting star" |
| Orbits |
|
Comets of short period P< 200 лет, долгого периода - P >200 years; the shape of the orbits is elongated ellipses | Diverse |
| Medium sizes | From tens of meters to hundreds of kilometers | Core - from 1 km to tens of km; tail ~ 100 million km; head ~ 100 thousand km | From micrometers to meters |

4. Complete the sentences.
Option 1.
Remnant of a meteorite body that did not burn up in earth's atmosphere and falling to the surface of the Earth is called a meteorite.
Comet tails can exceed millions of kilometers.
The nucleus of a comet is made up of space dust, ice and frozen volatile compounds.
Meteor bodies break into the Earth's atmosphere at speeds of 7 km / s (burn in the atmosphere) and 20-30 km / s (do not burn).
A radiant is a small area of the sky from which the visible paths of individual meteors of a meteor shower diverge.
Large asteroids have their own names, for example: Pallas, Juno, Vesta, Astrea, Hebe, Iris, Flora, Metis, Hygiea, Parthenope, etc.
Option 2.
A very bright meteor, visible on Earth as a fireball flying across the sky, is a fireball.
Comet heads reach the size of the Sun.
The tail of a comet is made up of rarefied gas and tiny particles.
Meteor bodies flying into the Earth's atmosphere glow, evaporate and completely burn out at altitudes of 60-80 km, larger meteorite bodies can collide with the surface.
Solid fragments of the comet are gradually distributed along the comet's orbit in the form of a cloud stretched along the orbit.
The orbits of most asteroids in the solar system lie between the orbits of Jupiter and Mars in the asteroid belt.
5. Is there a fundamental difference in the physical nature of small asteroids and large meteorites? Justify your answer.
An asteroid becomes a meteorite only when it enters the Earth's atmosphere.
6. The figure shows a diagram of the meeting of the Earth with a meteor shower. Analyze the drawing and answer the questions.
What is the origin of a meteor shower (a swarm of meteor particles)?
A meteor shower is formed from the decay of cometary nuclei.
What determines the period of revolution of a meteor shower around the Sun?
From the period of revolution of the parent comet, from the perturbation of the planets, the speed of the ejection.
In what case will the greatest number of meteors be observed on Earth (meteor, or stellar rain)?
When the Earth crosses the main mass of particles of the meteor swarm.
How are meteor showers named? Name some of them.
According to the constellation where the radiant is located.
7. Draw the structure of a comet. Specify the following elements: core, head, tail.
