Astronomers utilizing the NASA/ESA/CSA James Webb Space Telescope have actually identified a formerly unidentified small moon– provisionally designated S/2025 U 1– orbiting Uranus. Made in a series of Webb images handled February 2, 2025, the detection brings Uranus’ overall moon count to 29.

Found in the external Solar System, Uranus is the seventh world from the Sun.
Referred to as ‘the sideways world’for its severe axial tilt, the cyan-colored ice giant has a deep environment made up of hydrogen, helium and methane.
Uranus’ 28 moons consist of 5 significant moons– Titania, Oberon, Umbriel, Ariel and Miranda– found in between 1787 and 1948.
Called ‘the literary moons,’ Uranus moons are called for characters in Shakespeare and the works of Alexander Pope.
Astronomers believe Uranus’ bigger moons are approximately equivalent parts water ice and silicate rock.
“As part of Webb’s visitor observer program, we discovered a formerly unidentified satellite of the ice giant,” stated Dr. Maryame El Moutamid, a scientist at Southwest Research Institute.
“This things, without a doubt the tiniest things found to date, was discovered in a series of 10 long direct exposures acquired by Webb’s Near-Infrared Camera (NIRCam).”
The brand-new moon, provisionally designated S/2025 U 1, is at the edge of Uranus’inner rings.
The item is approximated to be simply 10 km(6 miles )in size, presuming it has a comparable reflectivity(albedo)to Uranus ‘other little satellites.
It lies about 56,250 km (35,000 miles)from its center in the world’s equatorial aircraft, in between the orbits of Ophelia and Bianca.
Ophelia has to do with 43 km (13 miles) in size, while Bianca is an extended item around 64 by 46 km (40 by 29 miles) in measurement.
“It’s a little moon however a substantial discovery, which is something that even NASA’s Voyager 2 spacecraft didn’t see throughout its flyby almost 40 years back,” Dr. El Moutamid stated.
S/2025 U 1 is the 14th member of the elaborate system of little moons orbiting inward of the biggest moons Miranda, Ariel, Umbriel, Titania, and Oberon.
“No other world has as numerous little inner moons as Uranus, and their intricate inter-relationships with the rings mean a disorderly history that blurs the limit in between a ring system and a system of moons,” stated Dr. Matthew Tiscareno, a scientist at the SETI Institute.
“Moreover, the brand-new moon is smaller sized and much fainter than the tiniest of the formerly understood inner moons, making it most likely that much more intricacy stays to be found.”
