‘Once-in-a-century’ crater discovered on Moon (PHOTOS)

    The feature was created by the impact of a comet or asteroid the size of a three- to six-story building, according to NASA

    The largest newly formed crater ever discovered in the solar system has been found on the Moon, in what scientists have described as a once-in-a-century impact event.

    The crater, measuring 222 meters (728 feet) across and 43 meters deep, was identified using images from NASA’s Lunar Reconnaissance Orbiter Camera (LROC), according to a study published in Science Advances on Wednesday.

    Researcher Robert Wagner first spotted the feature during a routine check of images taken by LROC’s Wide-Angle Camera in October 2025. Scientists then used higher-resolution observations over the following months to measure the crater and examine the surrounding terrain.

    According to NASA, the crater formed between April 11 and May 22, 2024, when a comet or asteroid roughly the size of a three- to six-story building slammed into the lunar surface.
