What?! Haven't you talked to Lou Frank? One of those hits us just
about every two or three seconds! -:) <snip>

Here's a NASA video of the impact of an estimated 10cm meteor on the
Moon on May 2. The video shows the fireball:

The NASA article recites estimates for the meteor and crater at:

Explosive equivalent: 4 kilotons TNT
Meteor size: 25cm
Crater size: 14 meters dia., 3 meters deep

Nice to know nature's Star Wars shield keeps us relatively safe from
