Uranus is the seventh planet from the Sun, and it's the third largest planet in our solar system – about four times wider than Earth. The diameter at its equator is 31,763 miles (51,120 kilometers). Uranus is a very cold and windy planet.
Uranus, seventh planet in distance from the Sun and the least massive of the solar system’s four giant, or Jovian, planets, which also include Jupiter, Saturn, and Neptune. At its brightest, Uranus is just visible to the unaided eye as a blue-green point of light. It is designated by the symbol ♅.
- When was Uranus discovered?Uranus was discovered on March 13, 1781, by the English astronomer William Herschel with the aid of a telescope. Uranus is the first planet to be d...
- How far is Uranus from the Sun?The mean distance of Uranus from the Sun is nearly 2.9 billion km (1.8 billion miles), more than 19 times as far as Earth, and it never approaches...
- What is the average temperature in Uranus's atmosphere?On average, Uranus radiates the same amount of energy as an ideal, perfectly absorbing surface at a temperature of 59.1 kelvins (K; −353 °F, −214 °...
- How many moons and rings does Uranus have?Uranus has 27 known moons that are accompanied by at least 10 narrow rings. Generally, the rings are located closer to the planet than the moons. S...
- What is unusual about the axis of Uranus?Unlike most planets, the axis of Uranus lies almost parallel to its orbital plane, which means that the planet spins nearly on its side, its poles...
Uranus is a very cold and windy world. The ice giant is surrounded by 13 faint rings and 28 small moons. Uranus rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus appear to spin sideways, orbiting the Sun like a rolling ball.
Uranus is the only planet whose equator is nearly at a right angle to its orbit, with a tilt of 97.77 degrees – possibly the result of a collision with an Earth-sized object long ago. This unique tilt causes the most extreme seasons in the solar system.
Jan 18, 2017 · Uranus, the seventh planet from the sun, may initially look like a bland, blue-green ball. But there's a lot to love about the icy giant, from its 13 rings to its 27 known moons to the fact that...
May 6, 2024 · Uranus is an ice giant (instead of a gas giant). It is mostly made of flowing icy materials above a solid core. Uranus has a thick atmosphere made of methane, hydrogen, and helium. Uranus is the only planet that spins on its side. Uranus spins the opposite direction as Earth and most other planets. Time on Uranus.
