OverviewAI-generated
Uranus is an ice giant and outer planet in the outer Solar System, orbiting the Sun. It was discovered by William Herschel on March 13, 1781, and named after Uranus and Urania. The planet has an atmosphere and includes the moons Cordelia, Ophelia, Bianca, and Cressida.
Its orbital characteristics include a semi-major axis of 2870658186, an eccentricity of 0.04725744, and an inclination of 6.48. The argument of periapsis is 170.95427630, and the longitude of the ascending node is 74.01692503. The synodic period is 369.66. Uranus has a radius of 25559, a mass of 86810, and a flattening of 0.0229. It is represented by the Uranus symbol.

Der Uranus (Latinisierung von altgriechisch οὐρανός uranós, deutsch ‚Himmel‘) ist von der Sonne aus mit einer durchschnittlichen Sonnenentfernung von 2,9 Milliarden Kilometern der siebte Planet im Sonnensystem und wird zu den Eisriesen gerechnet. Er wurde am 13. März 1781 von Wilhelm Herschel entdeckt und ist nach dem griechischen Himmelsgott Uranos benannt. Er ist damit als einziger Planet nach einem Gott der griechischen Götterwelt benannt. Der Durchmesser dieses Riesenplaneten ist mit über 51.000 Kilometern etwa viermal so groß wie der Durchmesser der Erde, das Volumen ist etwa 64-mal so groß wie das der Erde. Physikalisch ist Uranus mit dem Neptun vergleichbar und nimmt nach ihm mit rund 14 Erdmassen in der Massenrangfolge im Sonnensystem unter den Planeten den vierten Platz ein. Hinsichtlich des Durchmessers liegt er knapp vor Neptun auf Rang drei – nach Jupiter und Saturn. Das astronomische Symbol des Uranus ist dem Marssymbol ähnlich. Im Unterschied zu diesem hat der Kreis einen Zentralpunkt, und der Pfeil auf dem Kreis steht senkrecht. Ein anderes, hauptsächlich in der Astrologie verwendetes Uranussymbol ist . Uranus ist nur unter sehr günstigen Umständen freiäugig sichtbar, im kleinen Fernglas aber schon gut zu sehen. Seine blassgrüne Scheibe ist von der Erde aus betrachtet etwa 3,5″ groß. Mit Stand 2020 steht Uranus im Sternbild Widder und ist damit am Herbst- und Winterhimmel gut zu beobachten. Er läuft auf der Ekliptik um gut 4° pro Jahr nach Osten, 2024 wird er ins Sternbild Stier eintreten.
