Sometimes, two planets are so close that the two circles intersect (in the processing GUI).
Sometimes, the mass difference is so big that a planet is completely hidden behind a big sun.
This is evil. I cannot really think of a good solution yet.
Another remark :
Currently, the distance threshold under which two planets fuse is not a function of planet size. This behaviour sometimes gives false (graphic) impressions.
