About the Object
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.The semi-major axis of Uranus's orbit about the sun is 19.18 Astronomical Units (A.U.) or roughly 2.9 billion km. Moon S/2003 U 1 is 60,600 miles (97,700 km) away from Uranus. Moon S/2003 U 2 is 46,400 miles (74,800 km) away from Uranus.
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.The planet (without rings) has a diameter of roughly 32,000 miles (51,000 km) at the equator. MoonS/2003 U 1 is 10 miles (16 km) wide. Moon S/2003 U 2 is 8 miles (12 km) wide.
