S/2023 U 1 is the smallest and faintest natural satellite of Uranus known, with a diameter of around 8–12 km (5–7 mi). It was discovered on 4 November 2023 by Scott S. Sheppard using the 6.5-meter Magellan–Baade Telescope at Las Campanas Observatory, Chile, and later announced on 23 February 2024. [1]
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, shifting how astronomers understood the mysterious world.
MUSE (Mission to Uranus for Science and Exploration [3]) is a European proposal for a dedicated mission to the planet Uranus to study its atmosphere, interior, moons, rings, and magnetosphere. [ 2 ] [ 4 ] It is proposed to be launched with an Ariane 6 in 2026, travel for 16.5 years to reach Uranus in 2044, and would operate until 2050.

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.
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]
Retrograde irregular satellites of Uranus. Ferdinand is the most distant known satellite of Uranus. It follows a retrograde, modestly inclined but highly eccentric orbit. The diagram illustrates the orbital parameters of the retrograde irregular satellites of Uranus (in polar co-ordinates) with the eccentricity of the orbits represented by the segments extending from the pericentre to the ...
