Meteor
A meteor is the visible path of a meteoroid that enters the Earth's (or another body's) atmosphere, commonly called a shooting star. The visibility is due to the heat produced by the atmospheric entry. A very bright meteor, brighter than the apparent magnitude of Venus, may be called a fireball or bolide.
If a meteoroid survives its transit of the atmosphere to come to rest on the surface, the resulting object is called a meteorite.
A meteor striking the Earth or other object may produce an impact crater.
A tektite
Molten terrestrial material 'splashed' from such a crater can cool and solidify into an object known as a tektite
