Oh hey, one of my friends linked me this in video form about a year ago, and I made a video where, as Phobos passes the sun, the Doom Level 1 music fades in and out.
Rings at a very basic level tend to be moons that could be, or could have been, if they were higher in orbit such that gravity wouldn't tear the moon apart. They can also be from moons or even planets colliding, the debris in the aftermath forming the rings, which if not too low in orbit, could reform into a moon as well, which seems likely to be how our own moon formed.
You'll get lots of full solar eclipses on Pluto but that's a boring one too. No birds to hear freaking out (government drones beeping about low power from solar panels). The Sun looks tiny, too. ★☆☆☆☆
Don't forget the fact that it's insanely cold, if you don't like the cold you really won't like it there. Some people it doesn't bother them much, I will never understand these people.
