The core is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium. Uranus has bands of clouds that blow around rapidly. But they are extremely faint.

It rotates sideways and with the vertical rings, it has the appearance that at one time something tipped it over on its side.
