But how did it end up being this pure in most parts of the Moon? The secondary event that explains it, notes the report, is what researchers are calling a crustal overturn. Old impure plagioclase was replaced by hot, pure plagioclase as the moon cooled rapidly. Asteroid hits, space dust, and other harsh space conditions could have also sheared away the surface impurities, notes the report.
These larger objects, about the size and mass of our Moon, are called protoplanets. The accumulation of material to form planets in this way is called accretion. The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous.As the gases coalesced to form a protosun, the temperature in the solar system rose.hese larger objects, about the size and mass of our Moon, are called protoplanets.
