Ennui is the fourth planet away from the star Opus, in the Vernouli System. It is an atypical barren, rocky world in that there are numerous ice deposits below the surface of the planet. Ennui has a retrograde rotation, causing Opus to rise in the west and set in the east. This world is regularly raided by the Imperial Patrol, as it has become something of a haven for pirates.

1 These sections were filled out using the excellent worldbuilding chapters in GURPS Space (fourth edition). I highly recommend you picking it out.

2 Some values, such as density or mass, are multiples of Earth’s values (so a density of 0.9 means nine tenths of Earth’s Density)
