Timocharis (crater)

Timocharis is a prominent lunar impact crater located on the Mare Imbrium.

The rim of Timocharis has a somewhat polygonal outline, with an outer rampart that extends over 20 kilometers in all directions.

The crater is likely to have been formed in the Eratosthenian, between 3.2 and 1.1 Billion years ago, as it lacks a prominent ray system, but has not been significantly eroded by impacts.

THere are also a number of smaller craters in the immediate vicinity - notably Heinrich, Landsteiner, and Pupin.

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