The pronunciation of the name Uranus preferred among astronomers is / ˈ jʊər ə n ə s / YOOR-ə-nəs, [1] with the long "u" of English and stress on the first syllable as in Latin Uranus, in contrast to / j ʊ ˈ r eɪ n ə s / yoo-RAY-nəs, with stress on the second syllable and a long a, though both are considered acceptable. [g]
For Uranus, two variant symbols are seen. One symbol, , invented by J. G. Köhler and refined by Bode , was intended to represent the newly discovered metal platinum ; since platinum, sometimes described as white gold [ a ] was found by chemists mixed with iron, the symbol for platinum combines the alchemical symbols for iron , ♂, and gold , ☉.
The poles of astronomical bodies are determined based on their axis of rotation in relation to the celestial poles of the celestial sphere. Astronomical bodies include stars, planets, dwarf planets and small Solar System bodies such as comets and minor planets (e.g., asteroids), as well as natural satellites and minor-planet moons.
Uranus has been the butt of a lot of jokes (stop giggling). And it doesn't help that it's huge — roughly four times the size of Earth — or gassy with an atmosphere comprised partly of methane.
A lone spacecraft's visit to Uranus may have left us with the complete wrong impression of the ice giant for nearly 40 years.. The strange, sideways-rotating planet – the third largest in our ...
The symbols for Uranus were created shortly after its discovery. One symbol, , invented by J. G. Köhler and refined by Bode , was intended to represent the newly discovered metal platinum ; since platinum, commonly called white gold, was found by chemists mixed with iron, the symbol for platinum combines the alchemical symbols for the ...
The exceptions are Venus [78] and Uranus, [79] which rotate clockwise, though Uranus's extreme axial tilt means there are differing conventions on which of its poles is "north", and therefore whether it is rotating clockwise or anti-clockwise. [80] Regardless of which convention is used, Uranus has a retrograde rotation relative to its orbit. [79]
The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively. In astronomy , axial tilt , also known as obliquity , is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane ; equivalently, it is the angle between its equatorial plane and orbital ...
