NASA said Sept 16 that a comet or asteroid the size of a three- to six-story building struck the Moon, carving a crater about 141 feet deep and as wide as three football fields.[^4]

Researchers believe the impact happened in the spring of 2024, following a collision between a comet or asteroid and the lunar surface.[^1] The object is estimated to be a fragment of an asteroid or comet, with a size comparable to a building three to six stories tall.[^2] A separate report likewise dates the crater's formation to the spring of 2024.[^3]

What struck is not pinned down beyond the fragment estimate, and the crater's location on the Moon has not been detailed in the reports. The timing and the scale of the object are the firm numbers so far.
