Simulation Of Giant Impact Formation of Exomoon

 
 

Hydrocode simulation of an impact of a Venus-sized rock/iron planet colliding with a six Earth-mass planet. The collision creates a disk of rock fragments, liquid, and vapor massive enough to create a moon of 0.1 Earth masses, large enough to be detected by Kepler. Colors indicate the density of material, with solids depicted by orange/red hues, and liquid/vapor depicted by green/blue hues.
