URANUS

PLANET OF UNFORTUNATE HOMOPHONES

Originally, Uranus was often mistakenly considered for a star - and then later,when it was officially discovered, for a comet! In fact, when Sir William Herscheloriginally called it a comet, he even(possibly mistakeningly) compared it toa planet.

PROPERTIES OF URANUS

15 times larger than Earth

15% the size of Saturn

20% the density of Earth

97.8° axial tilt (approx. parallel with the plane of the Solar System)

Uranus' atmosphere is composed of 82.5% Molecular Hydrogen, 15.2% Helium, and 2.3% Methane - however, this methane is particularly important, as its absorption of red light is what gives Uranus its trademark blue hue.

As opposed to its more violent sister planet, Neptune, Uranus' weather is relatively docile, almost stagnant and relatively dull compared to the awesome climates and weather that occurs on Neptune.

Uranus' largest moons are Oberon and Titania (below) discovered by wlliam Herschel in 1787. Ariel, the third largest moon is pictured above with Uranus and was discovered by William Lassel. There ar 27 known moons of Uranus. The Voyager 2 found that its inner moons are half waterhalf rock, and the outer moons are said to probably be captured asteroids.

Uranus' rings were discovered by stellar occultation- occurs when the light from a star is blocked by an interveining body when reaching an observer.

The dips in brightness indicated that the planet was encircled by five narrow rings. These rings are smaller than Saturn's.

The interior of Uranus is mostly composed of ice and rock; rather, mathane in the form of rock. This "warmer" ice is able to flow freely. Uranus has little mettalic hydrogen and more metallic rocky elements.
