An addon for OPM that adds these things: Mimas analogue - Mummus - looks like a giant eyeball with a LAVA-FILLED pupil Iapetus analogue - Ridga - has a very tall ridge and a tiny submoon Hyperion analogue - Hypo - a square and the kerbals' inspiration for the sponge Planet 9 analogue - Kohd - is a blue gas giant. moons: Who knows? planet 10 analogue - Tyke - has Very Large Rings and some asteroids Eris analogue - Ica - made of ice and has a very red moon
