Just some minor issues and some feedback.
1. The dwarf planet texture (at maximum zoom in) is quite blocky.
2. Star 'activity' stops working after a while after 30 - 40 mins.
3. Consider changing 'An undiscoverd world' to 'Unknown' or even back to '?' as it may not be a world at all, could be a Asteroid Belt, Wormhole e.c.t.
