Meteoroids are debris from comets and asteroids. So what is the term for a rock that travels from outside of the solar system?Answer Question

Some comets come from outside of the Solar system. Any rocky parts from comets would still be meteoroids. Your first question doesn't make much sense. A star is too hot to have rocks. Stars are made of plasma, which is completely ionized gas, the fourth state of matter. Rocks are crystallized, solid minerals. No star going supernova is going to hurl rocks into the the interstellar gas-dust medium as part of the bow shock wave in the interstellar medium created by the super nova. by ?DaveC??

The best you could hope for is a rock from a planet or asteroid which was orbiting the supernova. That said... Even if a rock comes from completely outside our solar system, enters the earth's atmosphere, and makes it to the surface; it would still be termed a meteorite. It would be difficult if not impossible to definitively determine the ultimate origin of such a rock. by Jz93 Member since:May 26, 2011Total points:314 (Level 2)Rocks cannot come from a supernova but if a planets debris destroyed by one came to earth, no huge pieces, there could possibly be some precious metals imbedded in the rock. The meteorite could be worth alot of money.
