´╗┐ Uranus : A Planet On Its Side
external image uranus.gif



Uranus is much smaller than Jupiter and Saturn, but with a diameter of 51,118 km, it is still over four times that of Earths.
It would take 15 of our planet to equal the mass of Uranus.

Though Uranus is the next planet out from Saturn, it is over twice Saturn's distance from the Sun. Being
28.69 x 108 km from the Sun, Uranus is a cold world
with an average temperature of -221 C above cloud tops. And clouds are all we have ssen of this distant cold world.
Even the Voyager spacecraft could not see
beyond those clouds.

Uranus was not known to the ancient astronomers who knew only those planets out to Saturn. Uranus was too distant
to be seen with the naked eye. This planet had to wait until 1781 when the astronomer William Herschel discovered
it while hunting for comets.
