Uranus is an oblate spheroid, which causes its visible area to become larger when viewed from the poles. This explains in part its brighter appearance at solstices. [16] Uranus is also known to exhibit strong zonal variations in albedo (see above). [10] For instance, the south polar region of Uranus is much brighter than the equatorial bands. [3]
Illustrations depict how Uranus' magnetosphere, or protective bubble, was behaving before Voyager 2's arrival (left) and during the spacecraft's flyby (right).
Uranus, blue-green in color due to the methane contained in an atmosphere comprised mostly of hydrogen and helium, has a diameter of about 31,500 miles (50,700 km). It is big enough to fit 63 ...
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.

Venus rotates clockwise, and Uranus has been knocked on its side and rotates almost perpendicular to the rest of the Solar System. The ecliptic remains within 3° of the invariable plane over five million years, [2] but is now inclined about 23.44° to Earth's celestial equator used for the coordinates of poles. This large inclination means ...
The first panel (left) of this artist's concept depicts how Uranus' protective magnetosphere behaved prior to Voyager 2's flyby. The second panel shows that unusual solar weather was happening at ...
Voyager 2 remains the only space probe to visit the Solar System’s ice giants — Uranus and Neptune — but new experiments and next-generation telescopes finally are revealing what makes these planets so strange, including how an ancient collision knocked Uranus onto its side; how a special ice cocktail reveals what powers super-huge ...
Voyager 2's visit to Uranus may have left us with the complete wrong impression of the ice giant for nearly 40 years, according to a new study. Voyager 2 is the only craft to visit Uranus. Its ...
