Science
Physical
- Radius (estimated)
- 4 km
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~8 km) could be off by a factor of two.
Orbit around Uranus
- Distance from Uranus
- 7,978,698 km
- From JPL orbital elements
- Orbital period
- 1.86 years
- From JPL orbital elements
- Eccentricity
- 0.1861
- From JPL orbital elements
- Inclination to the J2000 equator

Radiation & temperature
- Insolation
- 0.00265 S⊕ · 1/377 of the sunlight Earth receives
- Computed from the distance to the Sun (inverse-square; Earth's sunlight = 1), before any atmosphere.
Discovery & history
- By
- S.S. Sheppard
S/2023 U 1 is the provisional designation of a small moon of Uranus detected in 2023 by S.S. Sheppard. It has not yet been given a permanent name, and little is known about it beyond its discovery and orbit.
