Uranus
Uranus (Latinisation from ancient Greek οὐρανός uranós, English 'sky') is the seventh planet in the solar system from the Sun, with an average solar distance of 2.9 billion kilometres, and is counted among the ice giants. It was discovered on 13 March 1781 by Wilhelm Herschel and is named after the Greek sky god Uranos. It is thus the only planet named after a god of the Greek world of gods. The diameter of this giant planet is over 51,000 kilometres, about four times the diameter of the Earth, and its volume is about 64 times that of the Earth. Physically, Uranus is comparable to Neptune and, with about 14 Earth masses, takes fourth place after it in the mass ranking in the solar system among the planets. In terms of diameter, it is just ahead of Neptune in third place - after Jupiter and Saturn. Uranus is only visible with the unaided eye under very favourable conditions, but it can be seen well in small binoculars. Its pale green disc is about 3.5″ in size when viewed from Earth. As of 2020, Uranus is in the constellation of Aries, making it easy to observe in the autumn and winter skies. It moves eastwards on the ecliptic by a good 4° per year, and in 2024 it will enter the constellation of Taurus.
