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 in astronomy is called 'ice' or volatiles.
The exploration of Uranus has, to date, been through telescopes and a lone probe by NASA 's Voyager 2 spacecraft, which made its closest approach to Uranus on January 24, 1986. Voyager 2 discovered 10 moons, studied the planet's cold atmosphere, and examined its ring system, discovering two new rings. It also imaged Uranus' five large moons ...
The Uranus Orbiter and Probe is an orbiter mission concept to study Uranus and its moons. [1] The orbiter would also deploy an atmospheric probe to characterize Uranus's atmosphere. The concept is being developed as a potential large strategic science mission for NASA. The science phase would last 4.5 years and include multiple flybys of each ...
NASA released new images Monday that show Uranus, the seventh planet from the sun, in greater detail than ever before. The new images of Uranus were captured by the James Webb Space Telescope and ...
Uranus was the last giant planet without any known irregular moons until 1997, when astronomers using ground-based telescopes discovered Sycorax and Caliban. From 1999 to 2003, astronomers continued searching for irregular moons of Uranus using more powerful ground-based telescopes, resulting in the discovery of seven more Uranian irregular moons.
Puck is the largest inner moon of Uranus, orbiting inside the orbit of Miranda. It is intermediate in size between Portia (the second-largest inner moon) and Miranda (the smallest of the five major moons ). Puck's orbit is located between the rings of Uranus and Miranda. Little is known about Puck aside from its orbit, [4] radius of about 81 km ...
Miranda, also designated Uranus V, is the smallest and innermost of Uranus 's five round satellites. It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas, and named after Miranda from William Shakespeare 's play The Tempest. [10] Like the other large moons of Uranus, Miranda orbits close to its planet's ...
The scheme of Uranus 's ring-moon system. Solid lines denote rings; dashed lines denote orbits of moons. As currently understood, the ring system of Uranus comprises thirteen distinct rings. In order of increasing distance from the planet they are: 1986U2R/ζ, 6, 5, 4, α, β, η, γ, δ, λ, ε, ν, μ rings. [13]
