Eponym Jean Picard

Picard is a lunar impact crater that lies in the western part of the Mare Crisium. Selenographic coordinates are used to refer to locations on the surface of Earth 's Moon. Jean-Felix Picard ( July 21, 1620 &ndash July 12, 1682) was a French Astronomer and priest born in La Flèche In the broadest sense the term impact crater can be applied to any depression natural or manmade resulting from the high velocity impact of a projectile with larger body Mare Crisium (the "sea of crises" is a Lunar mare located in the Moon 's Crisium basin just northeast of Mare Tranquillitatis. To the west is the almost completely flooded Yerkes crater. Yerkes is a lunar crater near the western edge of Mare Crisium. Due eastward of Picard is the tiny Curtis crater. Curtis is a tiny lunar crater that lies in the western Mare Crisium, to the east of Picard crater. It is the largest crater on the mare, being slightly larger than Peirce crater to the north-northwest. The lunar maria (singular mare, two syllables are large dark Basaltic plains on Earth 's Moon, formed by ancient Volcanic eruptions Peirce is a small lunar crater that lies in the western part of Mare Crisium. The crater is named for 17th century French astronomer and geodesist Jean Picard. As a means of recording the passage of Time, the 17th Century was that Century which lasted from 1601 - 1700 in the Gregorian calendar Geodesy (dʒiːˈɒdɪsi also called geodetics, a branch of Earth sciences, is the scientific discipline that deals Jean-Felix Picard ( July 21, 1620 &ndash July 12, 1682) was a French Astronomer and priest born in La Flèche [1]

Picard is a crater from the Eratosthenian period, which lasted from 3. The Eratosthenian period in the Lunar geologic timescale runs from 3200 million years ago to 1100 million years ago 2 to 1. 1 billion years ago. Inside Picard is a series of terraces that seismologists have attributed to a collapse of the crater floor. The lowest point on the crater floor is approximately 2000 meters below its rim. [2] The crater rim of Picard is well-defined and shows little sign of wear, having a sharp-edged appearance. It has a small hill at the center. [3]

Satellite craters

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