| Usage

A meteoroid is a piece of rock, smaller than an asteroid and larger than a speck of dust, moving through space. A meteoroid becomes a meteor when it enters Earth’s atmosphere. A meteor becomes a meteorite when it hits the ground (which rarely happens, since most burn up in the atmosphere).

The adjective meteoric can mean of, relating to, or formed by a meteoroid—for example:

The meteoric origin of the event is supported by eyewitness accounts of a bluish light moving across the sky from east to north. [Salem News]

But meteoric is more often used in its metaphorical sense—like a meteor in brilliance, speed, or transience. It often appears in the phrase meteoric rise, which is a little illogical because meteors never rise. But writers have been using meteoric as a synonym of quick or short-lived for a long time, and this usage is widespread.

It’s more logical to use meteoric in reference to something that appears suddenly, has a moment of intensity, and quickly burns up or comes to a natural end. For example, these writers use meteoric well:
