This results in the odd fact that Uranus' polar regions receive more energy input from the Sun than do its equatorial regions. Uranus is nevertheless hotter at its equator than at its poles. The mechanism underlying this is unknown. Either its axial inclination is a bit over 90 degrees and its rotation is direct , or it's a bit less than 90 degrees and the rotation is retrograde . It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather that its material is more or less uniformly distributed.
L ike the other gas planets, Uranus has bands of clouds that blow around rapidly.
Further HST observations show even more activity. By 2007 the Sun will be directly over Uranus's equator. U ranus' blue color is the result of absorption of red light by methane in the upper atmosphere. There may be colored bands like Jupiter's but they are hidden from view by the overlaying methane layer. L ike the other gas planets , Uranus has rings .
