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, which astronomy calls "ice" or volatiles.

Dec 31, 2024 · Uranus is one of two ice giants in the outer solar system (the other is Neptune). Most (80% or more) of the planet's mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small rocky core.

An ice giant is a giant planet composed mainly of elements heavier than hydrogen and helium, such as oxygen, carbon, nitrogen, and sulfur. There are two ice giants in the Solar System: Uranus and Neptune.

May 13, 2022 · Like its neighbor Neptune, Uranus is known as an ice giant, meaning 80% or more of the planet's mass is a hot dense fluid composed of icy materials including water, methane, and ammonia,...

Feb 26, 2020 · Far-flung Uranus and Neptune — the ice giants of our solar system — are as mysterious as they are distant. Soon after its launch in 2021, NASA’s James Webb Space Telescope will change that by unlocking secrets of the atmospheres of both planets.

Dec 30, 2023 · Uranus, the seventh planet from the Sun, holds a unique position in our Solar System. It’s categorized as an ice giant, primarily due to its large size and its composition, which includes water, ammonia, and methane ice crystals, giving it a distinct pale blue color.

Nov 22, 2024 · Today’s Image of the Day from NASA Webb Images features an extraordinary view of Uranus, the seventh planet from the sun in our solar system. The photo reveals the rings, moons, and extreme seasons of the ice giant Uranus in unprecedented detail.

Mar 31, 2025 · The ice-giant planet Uranus, which travels around the Sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA’s Hubble Space Telescope have uncovered new insights into the planet's atmospheric composition and dynamics. This was possible only because of Hubble’s sharp resolution, spectral capabilities, and longevity.

Mar 5, 2025 · Uranus, the seventh planet from the Sun, is an ice giant planet in the outer solar system. Like Jupiter and Saturn, Uranus and its rings appear to mainly produce X-rays by scattering solar X-rays, but some may also come from auroras.

Feb 16, 2025 · Uranus is an ice giant, differing significantly from the gas giants Jupiter and Saturn due to its unique composition and internal structure. It is the third-largest planet in the solar system by diameter, measuring approximately 50,724 kilometers across, but it is only the fourth most massive, with a mass of about 8.68 × 10^25 kilograms.
