天王星 (太阳VII)是一颗位于太阳系的冰巨行星,它的自转轴极度倾斜,使其南北两极位于大多数其他行星的赤道位置上,因而具有不寻常的侧边倒的磁场。[1]

天卫五
Miranda is one of the smallest objects in the Sol System known to be in hydrostatic equilibrium. Its extreme and varied topography includes the Verona Rupes, which features the tallest cliff in the system.
天卫一
The surface of this moon is crisscrossed by an extensive network of scarps, canyons and ridges. Scientists speculate some of these canyons were carved out by liquid ammonia, methane or carbon monoxide.
天卫二
This moon's name has its roots in the Latin word "umbra", which means shadow. An appropriate reference considering Umbriel is the darkest of all Uranian moons.
天卫三
Titania is Uranus' largest moon. Enormous canyons and scarps cut through its surface. Scientists believe they were created after an interior expansion occurred during the moon's evolution.
天卫四
Uranus' second largest moon was named after a mythical faery king from a famous 16th century play. Its surface is covered in impact craters and appears red in color due to space weathering.
