Planetary collision simulations - from an asteroid to a Mars-sized planet

A set of collision simulations with gradually increasing impactor size. Other parameters are the same for all simulations, namely: - Impact angle 45° - Initial impact speed 10 km/s - Target is a differentiated Earth, with core (density 7860 kg/m^3) and mantle (density 3050 kg/m^3). Earth contains 2 million particles, number of particles in the impactor varies depending on its size. Computed with OpenSPH Join the Discord server: Music:
