Abstract: The discovery of S/1986 U 10 is presented including photometry and orbital elements. The new satellite orbits only 1200 km outside Belinda's orbit and very close to the 44:43 eccentric resonance with Belinda. Its radius of about 15 km is much smaller than that expected from the trend seen for the other 15 regular uranian satellites. The 10 uranian satellites previously discovered by Voyager 2 are about 20% brighter than determined previously. One of these satellites, Puck, had a measured size which was slightly revised to 81+/-2 km. The first size measurements for the other nine satellites yielded sizes 40% larger on average and up to 60% larger than previously estimated. Most of these satellites are nonspherical. Juliet and Belinda may be the most oblong satellites in the Solar System among satellites with measured shapes.
