Uranus' ring system was the second to be discovered in the Solar System, after that of Saturn. [9] In 1982, on the fifth anniversary of the rings' discovery, Uranus along with the eight other planets recognized at the time (i.e. including Pluto) aligned on the same side of the Sun. [10] [11]
The largest is located twice as far from Uranus as the previously known rings. These new rings are so far from Uranus that they are called the "outer" ring system. Hubble also spotted two small satellites, one of which, Mab, shares its orbit with the outermost newly discovered ring. The new rings bring the total number of Uranian rings to 13. [162]
James Ludlow Elliot (June 17, 1943 – March 3, 2011) was an American astronomer and scientist who, as part of a team, discovered the rings around the planet Uranus. [2] [3] Elliot was also part of a team that observed global warming on Triton, the largest moon of Neptune. [4] [5]
A ring system is a disc or torus orbiting an astronomical object that is composed of solid material such as dust, meteoroids, planetoids, moonlets, or stellar objects. Ring systems are best known as planetary rings, common components of satellite systems around giant planets such as the rings of Saturn, or circumplanetary disks.

Discovery of rings of Uranus Jessica Mink (formerly Douglas John Mink [ 1 ] ) is an American software developer and a data archivist at the Center for Astrophysics | Harvard & Smithsonian . [ 2 ] She was part of the team that discovered the rings around the planet Uranus .
The first reliable detection of a ring was made in 1968 by stellar occultation, although that result would go unnoticed until 1977 when the rings of Uranus were discovered. [2] Soon after the Uranus discovery, a team from Villanova University led by Harold J. Reitsema began searching for rings around Neptune. On 24 May 1981, they detected a dip ...
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
