Picard (crater)
Crater on the Moon
Picard is a lunar impact crater that lies in Mare Crisium. The crater is named for 17th century French astronomer and geodesist Jean Picard.[1] It is the biggest non-flooded crater of this mare, being slightly larger than Peirce to the north-northwest. To the west is the almost completely flooded crater Yerkes. To east of Picard is the tiny Curtis.
Picard is a crater from the Eratosthenian period, which lasted from 3.2 to 1.1 billion years ago.[2] Inside Picard is a series of terraces that seismologists have attributed to a collapse of the crater floor. It has a cluster of low hills at the bottom.[3]
