Stretching 2,500 kilometers in diameter and plunging up to 8 kilometers deep, the SPA basin is the largest confirmed impact structure on the Moon—and likely the largest in the entire solar system. Formed roughly 4.2 to 4.3 billion years ago, it predates most of the Moon’s other large basins. Its sheer scale means the impactor likely punched through the lunar crust and excavated material from the mantle, offering a rare window into the Moon’s deep interior.
