Geological Chronicle

Szilard is a damaged impact crater spanning 127.22 kilometers across the lunar far side, positioned east-northeast of Richardson and southeast of the walled plain Harkhebi. Situated between Harkhebi and Szilard is the small crater Giordano Bruno, whose ray system forms streaks across Szilard's rim and interior.

Subsequent impacts have heavily eroded and reshaped the crater's rim. The worn satellite crater Szilard H lies across the southeastern rim, while the interior floor is somewhat uneven in its western half and more level and featureless to the east.

Prior to its formal naming by the International Astronomical Union in 1970, the formation was known as Crater 116. The designation honors Hungarian-American physicist Leó Szilárd, who theorized nuclear chain reactions and worked on the atomic bomb during World War II.
