Question

write two main feature each of the following celestical bodies A asteroids B. comets​

Answer 1

Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago. Asteroids formed much closer to the Sun, where it was too warm for ices to remain solid

In astronomy, the word object and body are often used interchangeably. On the other hand, a celestial body is a solo, strongly bound, adjoining entity, while the celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.
