I vaguely recall there having been some posts about such, but can't seem to find them. So, I came across five planets all orbiting the same barycenter, around a single class K star, in a mass code C system. I'll post the system name once I sell the data (will probably be at least a couple of weeks), but in the meantime, here's how they all look:

Quite far from the star. Thanks to the distance and all having quite thin pure nitrogen atmospheres, they are all quite cold; the sixth planet out is actually considerably warmer, thanks to having a thick atmosphere (99.9% nitrogen, 0.07% methane, 1154.13 atm, 141 K.)
Pity that none of these are landable, but I think it's a cool find nonetheless.
