Blackett is a
lunarimpact 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 ridge features trending 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.
