Blackett (crater)
Encyclopedia
Blackett is a lunar
impact crater
that lies on the far side of the Moon
, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale
basin. The formation of that major feature has left Blackett deeply marked with groove-like features running from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.
Overall this crater is heavily eroded, with several craters overlaying the southern rim, and smaller formations overlaying the western and northwestern rim. The interior floor has been roughened by ejecta, leaving only parts of the southwest interior in their previous relatively level and featureless condition.

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...

Mare Orientale
Mare Orientale is one of the most striking large scale lunar features, resembling a target ring bull's-eye. Located on the extreme western edge of the lunar nearside, this impact basin is difficult to see from an Earthbound perspective.Material from this basin was not sampled by the Apollo program...
