Terby (crater)

Terby is a Martian impact crater located in the Noachis Terra region of Mars. It is situated at approximately 28.1° South latitude and 74.1° East longitude. The crater measures roughly 170 kilometers (106 miles) in diameter.

Terby is notable for displaying evidence of past lacustrine (lake-related) activity. Sedimentary deposits and delta-like features within the crater suggest that it once held a lake. These features make Terby a region of interest for scientists studying the history of water on Mars and the potential for past habitability.

The crater's floor exhibits layered deposits and evidence of erosion, indicating a complex history of sediment accumulation and modification. These layers may provide a valuable record of environmental conditions on early Mars. The central peak of Terby is also partially eroded, further indicating significant modification over time.

Observations from orbiting spacecraft, such as the Mars Reconnaissance Orbiter, have revealed details about the mineral composition and geological structure of Terby crater. These studies help scientists understand the processes that shaped the crater and its environment.
