The researchers created the numerical simulations using smoothed particle hydrodynamics software, considered the basis for a wide range of planetary collision studies, to model different scenarios ...

For nearly 40 years, scientists have generally agreed that Earth's Moon formed from debris after a massive collision with our ...

In the final phase of terrestrial planet formation, planetary embryos and planetesimals ... we use our recently developed GPU N-body code GANBISS. GANBISS treats all collision as perfect merging and ...

Something catastrophic like an interplanetary collision, perhaps. This catastrophic clashing theory has been in the works for a while now, and planetary scientists think that Mercury might have ...
