Where is the third rock from sol on spore?

The 3rd rock from sol is just earth- hence SOLar system- to find it you just look for the arm of the galaxy with what appears to have a spot or something on the end of the arm near the inside part of it then, some where near the middle of that arm is sol (near the middle segment pointing near the end of the arm- hope this helps!
