Uranus: The Tilted Ice Giant

Uranus, the seventh planet from the Sun, is an ice giant with a peculiar characteristic that sets it apart from all other planets: it rotates on its side. With an axial tilt of 98 degrees, Uranus essentially rolls around the Sun like a ball, making it one of the most unusual planets in our solar system.

An Ice Giant

While often classified with the gas giants, Uranus is more accurately called an "ice giant." Unlike Jupiter and Saturn, which are primarily hydrogen and helium, Uranus has a much larger proportion of "ices"—water, methane, and ammonia—in its interior. These ices exist under extreme pressure and temperature, creating exotic forms of matter not found on Earth.

The Sideways Planet

Uranus's extreme tilt is likely the result of a massive collision with an Earth-sized object early in the solar system's history. This unusual orientation means that during parts of its 84-year orbit, one pole faces the Sun continuously for 42 years of daylight, while the other experiences 42 years of darkness.

A Pale Blue World

Uranus appears as a pale blue-green sphere, a color caused by methane in its atmosphere absorbing red light and reflecting blue. Unlike the dramatic storms and features visible on Jupiter and Saturn, Uranus appears relatively featureless, though recent observations have revealed faint cloud bands and storms when viewed in infrared wavelengths.

Rings and Moons

Uranus has 13 known rings, much fainter and darker than Saturn's spectacular rings, composed primarily of dark particles. The planet also has 27 known moons, uniquely named after characters from the works of William Shakespeare and Alexander Pope, including Miranda, Ariel, Umbriel, Titania, and Oberon.
