Eponym Jean-Félix Picard

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.

Contents

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]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Picard. [4]

<span class="mw-page-title-main">Tebbutt (crater)</span> Crater on the Moon

Tebbutt is a lunar impact crater that is located near the southwestern edge of Mare Crisium. It was named after Australian astronomer John Tebbutt. It was formerly designated Picard G before being named by the IAU, and lies south of the crater Picard. To the north of Tebbutt, but farther east than Picard, is the flooded Lick.

<span class="mw-page-title-main">Peirce (crater)</span> Crater on the Moon

Peirce is a small lunar impact crater in the western part of Mare Crisium. That dark, circular lunar mare is located in the east-northeasterly part of the Moon's near side.
