Question

space rock is solid or any gas​

Answer 1

Answer:

Whatever they may be called, they have much to tell us about our solar system. The three main types of space rocks are comets, asteroids and meteoroids. Comets are the "dirty snowballs" of space. They are bodies of ice, rock, gas and dust.

Answer 2

Answer:

meteoroid

Whether a space rock is called a meteoroid, meteor, or meteorite, depends on where it is at any given time. While it is floating around in space, a space rock is called a meteoroid. Really small space rocks (space dust) are called micrometeoroids.
