In astrology, the planet Uranus () is the ruling planet of Aquarius. Because Uranus is cyan and Uranus is associated with electricity, the colour electric blue, which is close to cyan, is associated with the sign Aquarius (see Uranus in astrology). The chemical element uranium, discovered in 1789 by the German chemist Martin Heinrich Klaproth, was named after the then-newly discovered Uranus. "Uranus, the Magician" is a movement in Gustav Holst's orchestral suite "The Planets", written between 1914 and 1916.
