Science
Physical
- Radius (estimated)
- 11 km · 1% of our Moon's radius
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~22 km) could be off by a factor of two.

Radiation & temperature
- Insolation
- 0.00264 S⊕ · 1/379 of the sunlight Earth receives
- Computed from the distance to the Sun (inverse-square; Earth's sunlight = 1), before any atmosphere.
Discovery & history
- By
- J.J. Kavelaars, M. Holman, D. Milisavljevic, T. Grav
Francisco was discovered in 2001 by J.J. Kavelaars 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.
