Antoniadi is a large lunar impact crater that lies on the southern hemisphere on the far side of the Moon.

Attached to the eastern rim of Antoniadi is Numerov, another large, ancient crater similar to Minnaert.

[2] The outer rim of Antoniadi is generally circular, with an irregular edge that has multiple indentations all about the perimeter.

Only a single small craterlet of note lies across the interior wall, near the southeast edge of the rim.

The bottom of a small unnamed crater within Antoniadi crater was measured by the laser altimeter (LALT) instrument on board the Japanese Selenological and Engineering Explorer (SELENE) satellite to be the lowest point on the moon,[1] at Lunar latitude 70.43° S, longitude 187.42° E.[3] The point is 9.178 km below the average lunar geoid.
