Uranus spends its life spinning
on its side, like tipping Earth over until the North Pole points towards
the Sun. Uranus always has one pole in sunlight. While one
receives light for 42 years, the other receives total darkness.
Uranus has nine rings that were discovered in 1977 when the planet passed in front of a star. Scientists, expecting to see only Uranus, instead saw a distant star "wink" nine time before they saw the blue green giant. This "winking" or occultation is like looking at a light bulb and passing your fingers before your eyes. |
