Uranus

Uranus is the seventh planet from the Sun and the third-largest planet in the Solar System. It is a gas giant, primarily composed of hydrogen and helium, with traces of methane that give it a distinct blue-green color. Uranus is unique among the planets in that it rotates on its side, with an axial tilt of 98 degrees. This unusual orientation is thought to be the result of a collision with a massive object early in the planet's history. Uranus was discovered by Sir William Herschel in 1781 and named after the Greek god of the sky, Ouranos (in Hebrew: אורנוס, in Spanish: Urano, in French: Uranus, in German: Uranus). The planet has a system of 13 known rings and 27 known moons, named after characters from the works of William Shakespeare and Alexander Pope. Uranus is also notable for its extreme seasons, which last for over 20 years due to its long orbital period of 84 Earth years.
