Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which astronomy calls "ice" or volatiles. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature (49 K (−224 °C; − ...
e. In Greek mythology, Uranus (/ ˈjʊərənəs / YOOR-ə-nəs, also / jʊˈreɪnəs / yoo-RAY-nəs), [3] sometimes written Ouranos (Ancient Greek: Οὐρανός, lit. ' sky ', [uːranós]), is the personification of the sky and one of the Greek primordial deities. According to Hesiod, Uranus was the son and husband of Gaia (Earth), with whom ...
How did Uranus get its name? English astronomer William Herschel discovered the ice giant in 1781 and tried unsuccessfully to name it after King George III, according to NASA.
Uranus' ring system was the second to be discovered in the Solar System, after that of Saturn. [9] In 1982, on the fifth anniversary of the rings' discovery, Uranus along with the eight other planets recognized at the time (i.e. including Pluto) aligned on the same side of the Sun. [10] [11]
Astronomers have discovered three previously unknown moons around Uranus and Neptune, the most distant planets in our solar system. The find includes one moon spotted orbiting Uranus — the first ...
Uranus is the butt of a lot of jokes, but scientists pronounce the name of our seventh planet differently than, say, most giggling middle-schoolers.
The major moons of Uranus are thought to have formed in the accretion disc, which existed around Uranus for some time after its formation or resulted from a large impact suffered by Uranus early in its history. [31] [32] This view is supported by their large thermal inertia, a surface property they share with dwarf planets like Pluto and Haumea ...
In retrospect, after it was discovered, it turned out it had been observed many times before but not recognized, and there were others who made calculations about its location which did not lead to its observation. By 1846, the planet Uranus had completed nearly one full orbit since its discovery by William Herschel in 1781, and astronomers had ...
