These are the Nebular Hypothesis of Laplace, the Planetesimal Hypothesis of Chamberlin and Moulton, and the Capture Theory of See. Darwings theory of Tidal Friction is scarcely a distinct ...

Could Psyche be the core of the planetesimal body that struck Earth and resulted in the formation of the Moon? Colton Brooks ...

Using these measurements, and simulations of the physics of dust and planetesimal collisions, planetary scientists and astronomers have established that the dust-to-protoplanet process takes tens of ...

These meteorites would have been the fractured remains of early "unmelted asteroids," a type of planetesimal. Planetesimals ...

"Theoretical models of planetesimal and planet formation predicted that objects like this should be out there. And the very first Kuiper Belt planetesimal that we visit turns out to be one of them ...
