Fast facts on Uranus (the planet)'s inner moons: Cordelia, Ophilia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda, Perdita, Puck and Mab. For more solar system facts, check out the playlist: youtube.com/playlist?list=PLrLu47k41a8Rb0q7R0J1t0zD6YWkHZaes
This is a revival of an old video series I made in 2012 (focusing on solar system trivia), after getting the motivation to bring this back. The original videos are gone, but my 2013 editions of these videos can be found here: youtube.com/playlist?list=PLrLu47k41a8TbdKNhPm3gzaJE7iu0rxIr

I use the fast-facts format when there is not much information known on a moon or group of moons. I like to at least touch on each one in this series.
