Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. ... was named after the then-newly discovered Uranus. [172]
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.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The new study found that when Voyager 2 was taking its readings intense solar wind created conditions that happen 4% of the time, said Jamie Jasinski, a space plasma physicist at NASA’s Jet ...
Later they found four additional rings: one between the β and γ rings and three inside the α ring. [7] The former was named the η ring. The latter were dubbed rings 4, 5 and 6—according to the numbering of the occultation events in one paper. [8] Uranus' ring system was the second to be discovered in the Solar System, after that of Saturn ...
Three-decade old data may have just led scientists to make a new discovery about Uranus.
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 ...
The ice giants Uranus and Neptune live up to their name. Although humans have only ever sent one spacecraft (Voyager 2) toward these far-flung worlds, scientists have a pretty good idea that these ...
