Uranus and Ariel, 2006 – Annotated
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.

This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope. A single ramp filter was used to sample several wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: FR782N (750 nm ) Green: FR782N (770 nm) Red: FR782N (790 nm)

Uranus as Viewed from Earth – 1994, 1997, 2006
This diagram shows how the inclination of orbits of Uranus' moons have appeared increasingly more oblique over the past 12 years due to Uranus's orbit about the Sun. Hubble Space Telescope has been watching Uranus over that period and has traced, in detail, our changing view of...
Uranus/Ariel – Earth/Moon Size Comparison
This illustrates the relative sizes of Uranus, Earth and Earth's Moon. The images are shown at the proper relative size, but not the correct relative distance from each other. Uranus is approximately 31,000 miles (50,000 kilometers) in diameter, or about four times the size of...
