Trumpler (Martian crater)

This redirect is about the crater on Mars. For the lunar crater, see Trumpler (lunar crater).

Trumpler is a crater in the Phaethontis quadrangle of Mars, located at 61.8°S latitude and 150.8°W longitude. It measures approximately 78 kilometres (48 mi) in diameter and was named after Swiss-American astronomer Robert Julius Trumpler (1886–1956). The name was approved by IAU's Working Group for Planetary System Nomenclature in 1973.

Description

The first image below shows the relationship among three craters that are near each other. Keeler Crater is to the North of Trumpler Crater. After Keeler was formed, a later impact formed Trumpler Crater, and in the process destroyed part of Keeler.
