NASA researchers report finding a newly formed lunar crater, “McGetchin,” using a recent scan. The crater is about 730 feet (222 meters) wide and is described as a rare discovery because it is relatively young compared with most detected lunar impacts.

NASA says the crater likely forms during spring 2024 after a comet or asteroid hits the Moon. The object that created the crater is estimated to be roughly building-sized—about three to six stories high—based on scientists’ assessments of the impact and resulting features. The outlets agree on the crater’s size, its “once in a century” characterization, the comet/asteroid cause, and the likely timing in 2024, while they primarily differ in wording and emphasis.
