Examine this object carefully. You can see it is made entirely of solid rock and metal, with no ice on its surface or inside.

This is a detailed image of the asteroid Vesta. You can clearly see it is a massive, roughly spherical but lumpy body made of solid rock, heavily scarred with impact craters, floating in space with absolutely no ice or tail.
