bolide

(noun) An especially luminous meteor (sometimes exploding).

Synonyms: fireball

Usage: Nancy stared in awe through her telescope as a bolide rocketed into her view, shining brightly in the night sky.

A bolide (French via Latin from the Greek βολίς bolís, "missile") is an extremely bright meteor, especially one that explodes in the atmosphere. In astronomy, it refers to a fireball about as bright as the full moon, and it is generally considered a synonym for a fireball. In geology, a bolide is a very large impactor.

One definition describes a bolide as a fireball reaching an apparent magnitude of −14 or brighter — more than twice as bright as the full moon. Another definition describes a bolide as any generic large crater-forming impacting body whose composition (for example, whether it is a rocky or metallic asteroid or an icy comet) is unknown.

A superbolide is a bolide that reaches an apparent magnitude of −17 or brighter, which is roughly 100 times brighter than the full moon. Recent examples of superbolides include the Sutter's Mill meteorite and the Chelyabinsk meteor.

In the limit where the bolide just reached the surface, different cases might result in anything from a single crater several km in diameter, a group of small craters, or no crater at all.
The material of the bolide (porous ice vs. rock) and its compressibility must control the character of impactor break-up in the physical situations of Venus.

I surmise from Wilmar's post that bolide is not common in American English.
What about British English?

Also, is it ever used in English for Formula 1 cars?
(In Croatian we call Formula 1 cars bolides. Also, vehicles used to achieve land speed records, such as the Blue Bird.)

….

A sudden bright and streaking light that was viewed by the lad
one quiet evening last week , left him wondering if it was a bolide
or just some mystery that would never be solved.
