Answer:
Asteroids or planetoids are small solids in planetary systems. They usually orbit the parent star in their own orbit or as natural satellites (moons) of larger planets.
A comet is a celestial body that is in an elliptical orbit around the Sun. They come from the farthest and coldest areas of the solar system.
Explanation:
The moon is the only natural satellite of the Earth and at the same time the closest celestial body.
It is the brightest celestial body in the night sky, not because it consists of incandescent gases like the sun, but because it reflects sunlight.
A planet is a celestial body that moves directly in an elliptical orbit around a star, not like a natural satellite, which orbits a star while circling around another body.
