Science
Physical
- Radius (estimated)
- 16 km · 1% of our Moon's radius
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~32 km) could be off by a factor of two.

Discovery & history

Stephano was discovered in 1999 by B. Gladman and colleagues. Uranus's moons are named after characters from the plays of Shakespeare and the poetry of Alexander Pope. Beyond its discovery and naming, little more about it has been individually recorded.
