Thebit (crater)

Thebit is a lunar impact crater located on the southeast shore of Mare Nubium. To the north-northwest is the crater Arzachel, and Purbach lies to the south-southwest. To the southwest is the flooded remnants of Thebit P, which is actually larger in diameter than Thebit itself.

Other craters near Thebit

The rim of Thebit is generally circular in outline, with a double-notch in the southwest wall. A prominent bowl-shaped crater, Thebit A, lies across the west-northwestern rim. The west-northwestern rim of this crater is overlain in turn by the even smaller Thebit L. Together this forms an elegant arrangement that makes Thebit relatively simple to identify. The floor of Thebit crater is rough and has no central peak. The rim displays a terrace, and has a hilly outer rampart.

Due west of Thebit is a 110-kilometer-long ridge named Rupes Recta, which rises to 240 meters. This linear feature runs north-northwest to south-southeast across the Mare Nubium.

Name

Thebit is a Latinization of the name of the 9th century Syrian astronomer and mathematician Thābit ibn Qurra.[1]

Satellite craters

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

gollark: It actually seems like the whole setup handling them is deliberately byzantine and overcomplicated to stop this sort of thing.
gollark: I am annoyed by how hard Amazon makes it to get the ebooks I bought (realistically, bought a license to legally) out of their walled garden and onto Calibre in some sort of actually standard format. Apparently I can't get any sort of usable files off the Android app, and I've lost my actual Kindle hardware, so I've had to download some ancient version of their Windows client and run it in Wine.
