Tannerus (crater)
Encyclopedia
Tannerus is a small lunar
crater
that is located in the rugged southern highlands of the Moon
. It lies within a couple of crater diameters of Asclepi
to the northeast, and some distance due east of Jacobi
.
The rim of this crater is very close to circular, with only a slight inward bulge along the north edge where it is joined to Tannerus P. The edge is sharp and well-defined, although there are tiny impacts along the rim in the west and south. The crater floor is level and free of markings or features of note.
Moon
The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Asclepi (crater)
Asclepi is a heavily worn lunar crater that lies in the rugged southern highlands of the Moon. The outer rim has been worn down and rounded by many millions of years of subsequent impacts, so that it is now nearly level with the surrounding terrain. As a result the crater is now little more than a...

Jacobi (crater)
Jacobi is a lunar crater that is located in the southern highlands on the near side of the Moon. It lies southeast of the crater Lilius, with Cuvier to the north-northwest and Baco to the northeast. The crater is 68 kilometers in diameter and 3.3 kilometers in depth...
