The Geminid meteor shower peaked overnight on Dec. 13 and 14, lighting up the skies as impressive meteors struck Earth's atmosphere. But Earth wasn't the only target; the moon is regularly bombarded with such meteors, and Daichi Fujii, the curator of the Hiratsuka City Museum in Japan, has captured some of the most recent collisions.

Fujii documented meteor impacts on the moon on Dec. 6, Dec. 7 and twice on Dec. 8, 2024, using cameras set to monitor Earth's nearest neighbor. You can view some of his lunar impact videos (as well as some impressive fireballs) on his X account.

"There was another lunar impact flash tonight. I filmed it at 360fps from my home at 22:34:35 on December 8, 2024 (slow playback) and was able to confirm it with multiple telescopes. Bright meteors and fireballs have been appearing every day, but lunar impact flashes have also been captured one after another," Fujii wrote in a post on X on Dec. 8.

It's unclear if the recent lunar impacts captured by Fujii are the product of the Geminid meteor shower or simply the result of sporadic meteors. When asked about the possible origin of these meteors, Robert Lunsford, of the American Meteor Society, told EarthSky, "While it’s a bit early for strong Geminid activity, it's possible that these are Geminid meteors as they are striking the moon from the expected direction."

Lunsford suggested that, if they are indeed Geminid meteors, the rate of lunar strikes is quite extraordinary, as even during the Geminid maximum, it's more typical to see less than one visible strike per night.

Given the moon's history with Geminid impacts, there is a good chance that at least some of these meteor strikes were Geminids. In 2015, NASA published a study on Geminid meteor shower lunar impact observations and found 19 such strikes in 2006 and 21 in 2010. Astonishingly, 55% of all impacts witnessed on the moon in 2010 were attributed to the Geminids.

However, Fuijii is not ruling out the possibility that they are simply sporadic meteors. "Given the position of the radiant, there is a possibility that these lunar impact flashes are associated with the Geminid meteor shower. However, since sporadic meteors still outnumber Geminids in ground-based meteor observations, they may be sporadic meteors," Fujii told EarthSky.

As the moon has virtually no atmosphere, when an object strikes the moon it does so at high speeds with nothing to slow it down. When a meteoroid collides with the moon, most of the energy from the impact is converted into heat and the formation of a crater. A smaller amount of the energy, however, is released as visible light, creating a bright flash at the collision site, according to NASA
