Hey Space Placers!
On March 17th the Moon was hit by the largest impactor yet recorded. NASA and amateur astronomers have been watching the Moon for these impacts from small space rocks and/or small comet bits. 100's have been recorded in video records.
The hit on March 17th was from a small boulder traveling at an estimated 57,000 mph. The impact formed a small crater about 20 meters across and released about 5 tons of energy. This event was recorded as well.
