>>>It didn’t explode, it grazed the atmosphere, and went on its way.

People on FR are so smart...much smarter than all the astronomers and astrophysicists which state it exploded.

And BTW...it did explode. That is the reason for the sudden brightening and the twin trails that were one trail...then two after the explosion.

Now...some of it...maybe most of it did skip off into the atmosphere. However, no doubt pieces of it made it to earth.

Here’s the FR word of the day!

BOLIDE - a meteor and meteorite related term, with specific definitions from several groups. One definition describes them as fireballs reaching magnitude -14 or brighter.[1] In geology the term is used “to imply that we do not know the precise nature of the impacting body ... whether it is a rocky or metallic asteroid, or an icy comet, for example”.[2]

An especially bright meteor, a bolide (in astronomy).
The word bolide comes from the Greek (bolis), which can mean a missile.

The IAU has no official definition of “bolide”, and generally considers the term synonymous with “fireball”. However, the term generally applies to fireballs reaching magnitude -14 or brighter.[1] Astronomers tend to use “bolide” to identify an exceptionally bright fireball, particularly one that explodes (sometimes called a detonating fireball). It may also be used to mean a fireball which creates audible sounds.

If the magnitude of a bolide reaches -17 or brighter it is known as a superbolide.
