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.
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.Uranus (without rings) has a diameter of roughly 32,000 miles (51,000 km) at the equator.
