There's a new game on steam that allows you to play around with the solar system. Move planets around, make them bigger, etc. Only $3.99
Seems very intuitive too use. As you can see in the screen shot it was easy for me to make Mars the same mass, density and size as Earth.
Perfect for people interested in ASB timelines.
