About Uranus in brief

Summary UranusUranus is the seventh planet from the Sun. Its name is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the grandfather of Zeus and father of Cronus. It has the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K. The Uranian system has a unique configuration because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. Sir William Herschel first observed Uranus on 13 March 1781, leading to its discovery as a planet. Voyager 2 remains the only spacecraft to visit the planet. Observations from Earth have shown seasonal change and increased weather activity as Uranus approached its equinox in 2007. It is likely to be a regular moving planet in an eccentric orbit around the sun, as a very moving comet in a very flummoxed orbit would be very difficult to observe. The sequel to Uranus: The Planets of the Sun has been published by The Astronomer’s Almanac, priced £16.99, and is available on Amazon.com and other online bookshops.

Uruus is a planet in the solar system, but it was never recognised as a. planet by ancient observers because of its dimness and slow orbit. It was generally mistaken for a star. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus as ‘ice giants’ to distinguish them from the other gas giants. Like the other giant planets,. Uranus has a ring system, a magnetosphere, and numerous moons. It has a complex, layered cloud structure.
