Origins of Uranus` oddities explained by Japanese astronomers
(PHYSorg.com Space & Earth)

The ice giant Uranus` unusual attributes have long puzzled scientists. All of the planets in the solar system revolve around the sun in the same direction and in the same plane, which astronomers believe is a vestige of how our solar system formed from a spinning disc of gas and dust. Most of the planets also rotate in the same direction, with their poles orientated perpendicular to the plane in which the planets revolve. However, uniquely among all the planets, Uranus is tilted at about 98 degrees.
