Zeno (crater)
Encyclopedia
Zeno is a lunar
impact crater
located near the northwestern limb of the Moon
. It lies to the east-southeast of the crater Mercurius
. Farther to the east of Zeno, along the limb, is the well-formed crater Boss
.
The rim of Zeno is slightly distorted and has received some erosion due to subsequent impacts. There is a depression in the surface attached to the eastern rim, forming a bulging extension. Small craters lie on the southern rim and across the interior of the northern wall. The crater Zeno B is attached to the exterior of the southwestern rim, and the distorted Zeno A is attached in turn to the western rim of Zeno B.
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...

Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

Mercurius (crater)
Mercurius is a lunar impact crater that is located in the northeastern part of the Moon. It lies to the northeast of the smaller crater Carrington, and west-northwest of Zeno. Just to the south is the small lunar mare named Lacus Spei, and to the west is the larger Lacus Temporis.The rim of...

Boss (crater)
Boss is a lunar impact crater that is located along the northeast rim of the Moon's near side. Due to its location, the crater is viewed from the side by observers on the Earth, and its visibility is subject to libration effects....

Satellite craters
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 Zeno.| Zeno | Latitude | Longitude | Diameter |
