3 days ago · ammonium hydrosulfide. methane hydrate. Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, astronomy calls "ice" or volatiles.
Jun 1, 2024 · Uranus, seventh planet in distance from the Sun and the least massive of the solar system’s four giant, or Jovian, planets. Uranus has more than two dozen moons, five of which (Umbriel, Miranda, Ariel, Titania, and Oberon) are relatively large, and a system of narrow rings.
- 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...
- 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...
- 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 °...
- 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...
- 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...
Jun 13, 2024 · 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.
Jun 1, 2024 · Uranus - Rings, Moons, Atmosphere: The rings of Uranus were the first to be found around a planet other than Saturn. The American astronomer James L. Elliot and colleagues discovered the ring system from Earth in 1977, nine years before the Voyager 2 encounter, during a stellar occultation by Uranus—i.e., when the planet passed ...
Jun 1, 2024 · Uranus - Gas Giant, Rings, Moons: At Uranus’s distance from the Sun, the planet takes slightly more than 84 Earth years, essentially an entire human life span, to complete one orbit.
1 day ago · Uranus is an ice giant planet, primarily composed of water, methane, and ammonia, and has the coldest atmosphere in the solar system with temperatures that can dip down to -224°C (-371°F). The planet has a tilted axis of rotation, which causes it to rotate on its side with its poles pointing towards the sun.
5 days ago · Summary. Uranus provides a unique laboratory to test current understanding of planetary atmospheres under extreme conditions. Multi-spectral observations from Voyager, ground-based observatories, and space telescopes have revealed a delicately banded atmosphere punctuated by storms, waves, and dark vortices, evolving slowly under the seasonal influence of Uranus’s extreme axial tilt.
