11.++Uranus

Uranus was discovered multiple times, but only once as a planet. Generally it has been mistaken as a star, though a few times it has been classfied as a "comet." Previously naming Uranus a comet himself, William Herschel was the first to name it for what it really was; a planet. March 3rd, 1781, Herschel was observing the planet under the starry night sky in his backyard. Writing in his journal, the entry recovered stated; "I don't know what to call it. It is as likely to be a regular planet moving in an orbit nearly circular to the sun as a Comet moving in a very eccentric ellipsis. I have not yet seen any coma or tail to it". Moving from a star to a comet, and a comet to a planet, careful observation is what included Uranus into our solar system.

Mythology Uranus is named after the ancient Greek god of the sky; he was father to Cronos and granfather of Zeus.

Mass The mass of Uranus is done in the equation: (8.6810 ± 0.0013) × 1025 kg, which is equivalent to the size of 14.536 earths.

Moons A moon is technically classified as a natural satellite, meaning the Moon, is a name in which we have called Earth's natural satellite. Uranus has 27 known natural satellites, with the five main moons being Miranda, Ariel, Umbriel, Titania and Oberon. Titania is the eighth largest moon in the solar system, with a radius of 788.9 km.

Diameter It's angular diameter is roughly 51,118 kilometers, compared to Earth's diameter of 12,756.2 kilometers.

Gravity The equtorial surface gravity is equal to 8.69 m/s2( meters per second squared or acceleration) and a 0.886 g -force.

Days The time it takes for Uranus to orbit around the Sun takes about 30,799.095 days. This is equal to 84.323 326 Earth years. 

Tilt of Axis The tilt of the axis is equal to 97.77°.

Distance The best distance estimated from Uranus to the Sun is 3 billion kilometers, 20 astronomical units (AU), or 1,784,000,000 miles.

Temp Range The temperature range of Uranus is 49 K to 57 K and the mean is 53 K at the 0.1 bar level. At the 1 bar level, the average temperature is 76 K.
