The Gliese 876 system is inaccurate, Gliese 876d is a gas giant, Gliese 876b, and c are terrestrial planets.
This isn't right, Gliese 876d is supposed to be the rocky planet, the others should be gas giants, not rock giants.
Please fix this in the next update.
Same problem with 16 Cygni Bb, it's a rocky planet when it should be a gas giant, Plus, 16 Cygni Bb is more jupiter sized rather than half its size.
Hope you fix that as well.
Chart Mode is on for Gliese 876 so that all the planets would be visible at once.
