The sideways planet
Uranus is the seventh planet from the Sun and an ice giant. Its most distinctive feature is its extreme axial tilt of 97.77 degrees, meaning it essentially orbits the Sun on its side. This is thought to be the result of a collision with an Earth-sized body long ago. Uranus has a blue-green color due to methane in its atmosphere, which absorbs red light. It has 27 known moons (all named after characters from Shakespeare and Alexander Pope), a faint ring system, and the coldest planetary atmosphere in the solar system at -224 degrees C.
