Trumpler (lunar crater)
Encyclopedia
Trumpler is a lunar
crater
on the far side of the Moon
, named after Robert Julius Trumpler
. It lies just to the south of the crater Nušl
, and northwest of Freundlich
. To the southwest is the heavily battered crater Tikhomirov
.
This is an old, eroded crater with an outer rim that has been damaged in places by subsequent impacts, especially along the southwestern section. The rim edge has been worn to the point where it is now poorly defined, and forms an uneven ridge in the surface. A short chain of small craterlets extends from near the crater mid-point to just outside the eastern rim. The southern interior floor is generally less impacted in the northern half.
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...

Freundlich (crater)
Freundlich is a lunar crater that is located on the far side of the Moon. It lies midway between the craters Trumpler to the north-northwest and the irregular Buys-Ballot to the south-southeast. This crater has a circular rim that is more heavily eroded at the northern and southern ends...
