Meteor impact on the Moon bright enough to see with the naked eye.
The impact of a 40kg meteor on the Moon on March 17 was bright enough to see from Earth without a telescope, according to NASA, who captured the impact through a Moon-monitoring telescope.
Now NASA’s Lunar Reconnaissance Orbiter will try and search out the impact crater, which could be up to 20 metres wide.
“On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium,” says Bill Cooke of NASA’s Meteoroid Environment Office. “It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before.”
Anyone looking at the Moon at the moment of impact could have seen the explosion–no telescope required. For about one second, the impact site was glowing like a 4th magnitude star.
Ron Suggs, an analyst at the Marshall Space Flight Center, was the first to notice the impact in a digital video recorded by one of the monitoring program’s 14-inch telescopes. “It jumped right out at me, it was so bright,” he recalls.
The 40 kg meteoroid measuring 0.3 to 0.4 meters wide hit the Moon traveling 56,000 mph. The resulting explosion1 packed as much punch as 5 tons of TNT.
This is simply the moon doing its job. Thank you, Moon.
