Uranus is the third largest planet in our Solar System. Uranus has nine major rings and 27 known moons. This image, taken by the Hubble Space Telescope in infrared reveals cloud structures not normally visible. Methane gas in the upper atmosphere absorbs red light, giving the planet its blue-green color. Uranus is spinning on its side, probably because of a collision with a large object early in the Solar System's history.


♅ Moon of Uranus: Bianca. 51km diameter. Discovered by Voyager 2 in 1986. Named after the sister of Katherine in Shakespeare's play 'The Taming of the Shrew'. Bianca belongs to the Portia Group of satellites, which also includes Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita. Its surface is grey in color. Virtually nothing is known about it, and no pictures exist showing what it actually looks like. Third closest moon to Uranus. CGI render by mr-nerb.

APOD: Verona Rupes, the tallest known cliff in the Solar System; This cliff is on Uranus' moon Miranda, and estimated to be 20 km deep, 10x the depth of the Grand Canyon. Due to Miranda's low gravity, it would take 12 mins for an adventurer to fall from the top, reaching speed of about 200 km/hr. Possibly related to a large impact or tectonic surface motion.
