That would be a meteoroid. The term "meteor" refers to the appearance or phenomenon as obsevered. The word itself refers originally to any atmospheric phenomenon, such as a cloud, or lightning.
The use of this general term for what we now think of as "meteors" has a similar history to the term UFO, which linguistically defers the question of identification, but in usage devolves to a particular conclusion.
It’s still not a meteorite if it’s in space. Has to hit the ground.
