The Largest Seen Lunar – Meteor Impact
On March 17, 2013 an object the size of a small boulder hit the Mare Imbrium region of Earth’s Moon. It exploded in a flash that was caught on camera. Had you been watching at the time of impact, you could have seen the glow of the explosion with the naked eye.
The explosion was as bright as a 4th magnitude star. The bolder was 0.3 to 0.4 meters in size, traveled at 56,000 mph and hit with an explosion that was equivalent to 5 tons of TNT.
The Lunar Monitoring Program is charged with monitoring the sky for similar impacts that might cause a threat to Earth. In the history of the program, this is the largest explosion seen to date.
This strike is believed to be part of a larger event that also effected the Earth. But because we have an atmosphere, the material that struck earth during the March 17th event burned up before hitting the ground. Something the Moon can’t do since it doesn’t have an atmosphere.
