查询词典 planetary

In the case of planetary formation, the gravitational interactions between the dust in the disk, the mass in the larger aggregates of material, and the sun itself plus the friction of the material, its thermal properties, and the interaction between the magnetic fields from the star and those of the disk material itself plus countless other factors may be vital in order to understand how planets like our own form from the primordial disk of stardust.
