* Meteoroid: This is the general term for any rocky or metallic body traveling through space. It can range in size from a grain of sand to a boulder.
* Micrometeoroid: This is a very small meteoroid, usually smaller than a grain of sand.
* Asteroid: This is a larger rocky body, typically bigger than a boulder. They orbit the Sun, often found in the asteroid belt between Mars and Jupiter.
* Comet: These are icy bodies that release gas and dust when they approach the Sun. They can be much larger than asteroids, but their composition is different.
So, depending on the specific size, the answer could be a meteoroid, a micrometeoroid, or an asteroid. If it's large enough and has a tail, it could be a comet.
