Question

Comets are _______ celestial bodies which moves about the solar system.​

Answer 1

Answer:

Comets are celestial bodies moving about the solar system in Elliptical orbits usually accompanied by a long shining tail. A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing.

Answer 2

Explanation:

Comets orbit the Sun just like planets and asteroids do, except a comet usually has a very elongated orbit. As the comet gets closer to the Sun, some of the ice starts to melt and boil off, along with particles of dust. These particles and gases make a cloud around the nucleus, called a coma.
