Sample Image by NHK CG group - My animations are not this beautifle yet...

SPH simulations of Giant Impact. Impactor (red) hits the protoearth (blue) from parabolic orbits. Time (shown in bottom-right corner) is in unit of 1100 seconds. In the following lists, M1 and M2 are the mass of the protoearth and that of the impactor, respectively. Jtotal is the total angular momentum of the system in unit of the current total angular momentum of the Earth-Moon system, J0

All movies are GIF animations. If you want to replay the movie, you may need to use xanim or some other animation viewer.
