2. A constellation is defined as an area where a group of stars forms a pattern that looks like an animal.
3. They are also like imaginary formations created by humans such as inanimate objects, and some mythological structures by connecting the dots of stars that people usually see in the sky.

In the case of option A,

1. Asteroids are known as minor planets that are rocky remnants of our solar system.
2. They are smaller in size than planets but of irregular shapes.
3. Asteroids orbit the sun.

In the case of option B,

1. A satellite is an object in space that orbits a planet.
2. There are two kinds of satellites- natural satellites and artificial satellite.
3. Moon is the natural satellite of earth.
4. Therefore, a satellite is also a part of our solar system.
5. Hence, option B is incorrect.

In the case of option D,

1. Comets are huge ice and dust particles that revolve around the Sun in an orbit.
2. Thus, comets are part of our solar system.
3. Hence, option D is incorrect.

Hence, option C is the correct answer.
