This one for example
The rarest ones.... are probably earth-likes as:

Earth-likes with rings
That last one (earth like with rings) I found last week on the 1st of april ohoh.
One thing I haven't seen so far... is a neutron star with rings. I know they exist, just haven't found one yet.
And then there is, speaking of rings...
this M star with rings
I have found it. I didn't record it's location, stupid. I crashed on a planet on my way back to the bubble. It's still out there somewhere at I think the edge of the core.
