Uranus blue tilted

Uranus, the seventh planet from the Sun, stands out for its blue-green color and extreme axial tilt of 98 degrees, causing it to rotate nearly on its side.

About this subject

Uranus is an ice giant composed mainly of hydrogen and helium, with a methane-rich atmosphere. Methane absorbs red light and reflects blue and green, giving the planet its distinctive color. Its axial tilt of about 98 degrees is unique in the Solar System, causing extreme seasons: each pole faces the Sun directly for 42 Earth years during its summer. Discovered by William Herschel in 1781, Uranus was the first planet found using a telescope. It has a faint ring system and 27 known moons, all named after characters from Shakespeare and Alexander Pope's works. The Voyager 2 spacecraft is the only one to have visited Uranus, in 1986, revealing details of its atmosphere and misaligned magnetic field.
