Question

Suppose an astronomer discovers a large, spherical-shaped body orbiting the Sun. The body is composed mostly of rock, and there are no other bodies sharing its orbit.

Answer 1

Answer:

The answer is "Comet".

Explanation:

The comets were interstellar frozen gas of snowballs, stone, and debris orbiting the sun, which are also the size of average towns while frozen. As even the orbit of the comet passes near the sun, it warms up and spreads dust and gas into a big floating head greater than most stars.  

• It is very important because they are primitive items left out from the galaxy creation.
• They were one of the first solid materials throughout the solar nebula, its collapsing interstellar-like cloud of dust and gas, which established the heat and planets.
