Comet
A comet is a ball of icy volatiles. This far from anywhere, it is just a dormant snowball with no tail or any chance of creating one. Roll a d6 to see how far it is from the ship. Technically, these aren't really comets, and some are better classed as kuiper-belt objects. But their make-up is very similar.
- 1D6 x 10 Mkm
- 1D6 x 25 Mkm
- 1D6 x 50 Mkm
- 1D6 x 100 Mkm
- 1D6 x 150 Mkm (1 AU) (+1 to Size roll)
- 1D6 x 2 AU (+2 to Size roll)
It will be moving vaguely in the ship’s direction (but is very unlikely to collide). Roll a D6 to see how quickly it is moving:
- 1D6 km/s
- 2D6 km/s
- 3D6 km/s
- 1D6 x 10 km/s
- 1D6 x 30 km/s
- 1D6 x 100 km/s. Roll again, on a 6 multiply by 10 and roll again.
Chance of the ship detecting it depends on what sort of sensor scans they are performing. It takes about 15 minutes to get a radio pingback from an object for every 1 AU it is in distance.

There is a 1 in 6 chance that the comet has some sign of civilisation.
- A radio beacon on it.
- There are a few empty cargo crates and signs of a makeshift landing site.
- This place has been mined, there is some equipment left behind.
- Some form of scout base, long since deserted.
- It is an old weapon's cache, still some weapons here.
- Old pirate base.
For the size of the settlement: 1-3) Small, 4-5) Medium, 6) Large.
