The moon is temporarily designated as S/2003 U 1 until the International Astronomical Union (IAU) formally certifies its discovery. S/2003 U 1 is orbiting 60,600 miles (97,700 km) away from the planet. If the satellite is as dark as Uranus's other moons, it is 10 miles (16 km) across, about the size of San Francisco. The Hubble telescope spotted S/2003 U 1 orbiting between the moons Puck, the largest satellite found by Voyager, and Miranda, the innermost of the five largest Uranian satellites. Astronomers previously thought this region was empty space. S/2003 U 1 whirls around the gas giant planet in 22 hours and 9 minutes. The white concentric lines at right are part of the planet's system of 10 rings. Several other moons can be seen orbiting just outside the rings. Credit: NASA, M.

The moon, Uranus's tiniest known satellite, is temporarily designated as S/2003 U 2 until the International Astronomical Union formally certifies its discovery. S/2003 U 2 is 8 miles (12 km) wide and orbits 46,400 miles (74,800 km) away from Uranus, circling the planet in 14 hours and 50 minutes. In this movie, the bright object below S/2003 U 2 is Belinda, whose orbital path is just 200 to 450 miles (300 to 700 km) from the new moon. The object above the new moon is another satellite, designated S/1986 U 10, seen here for the first time since the Voyager spacecraft snapped a picture of it in 1986. The white concentric lines at left are part of the planet's system of 10 rings. Several other moons can be seen orbiting just outside the rings. Credit: NASA, M.
