Uranus, the second-to-last planet from the Sun, is a faint greenish-blue disk due to its methane-rich atmosphere. Voyager 2's 1986 flyby provided most of our knowledge, revealing an atmosphere similar to Jupiter and Saturn but with more methane. Uranus' bland appearance is due to its cold temperature, which prevents cloud formation like Jupiter's. The planet has a core of heavy elements, surrounded by a mantle of ammonia and water, and a layer of hydrogen, helium, and methane. Uranus rotates on its side, causing extreme seasonal changes. It has 27 moons named after Shakespearean and Pope characters, and rings discovered through occultation.
