planetesimal
Molecular formula :
CAS :

nature : from the gas and dust of cohesion of the solar nebula, the gas dynamic interaction throwing dust concentration of the solar equatorial cloud intraday. The cloud-gravitational instability, the collapse ruptured, the cloud was different regions gathered many different chemical composition of the dust particles cluster. These collisions gravitational clusters of Health formed a ~ 10kin diameter, a few hundred kilometers to the different chemical composition of planetary accretion stage of the Herald Sun, said Xingzi. The solar system planets and satellites of the impact craters on the surface distribution, direct proof that the early formation of the solar system has many Xingzi exist.
