Rhaeticus is a lunar crater that lies astride the equator of the Moon, on the southeast edge of the Sinus Medii lunar mare. To the north-northwest is Triesnecker crater, and due south can be found the worn remnant of the Hipparchus walled-plain.
The outer wall of Rhaeticus is heavily disintegrated, with rifts and notches in the northeast. The wall is most intact along the eastern face, while in the northwest it is little more than a low rise in the surface. There is also a low cut in the south-southeast wall. The overall shape of the rim is that of a rough hexagon that is slightly elongated in the north-south direction. The interior has been resurfaced by lava, and only a few low rises remain in the surface. Beginning at the crest of the eastern wall is a chain of craterlets that continue to the east-northeast for about a crater diameter.

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 Rhaeticus crater.
