Technical facts about this news release: About the Object Object Name: Uranus Object Description: Planet Distance: The semi-major axis of Uranus's orbit about the sun is 19.18 Astronomical Units (A.U.) or roughly 2.9 billion km. Dimensions: Uranus (without rings) has a diameter of roughly 32,000 miles (51,000 km) at the equator. About the Data Data Description: This image was created from HST data from the following proposal 10805: PI: L. Sromovsky (University of Wisconsin, Madison), H. Hammel (Space Science Institute), and K. Rages (SETI Institute). Instrument: ACS/WFC Exposure Date(s): July 26, 2006 Filters: FR782N at 750nm, 770 nm, and 790 nm About the Image Image Credit: NASA, ESA, and L. Sromovsky (University of Wisconsin, Madison) Release Date: August 31, 2006 Colors 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: FR782N @750 nm blue FR782N @770 nm green FR782N @790 nm red Orientation/Scale: Uranus and Ariel - 2006 - Annotated [ http://imgsrc.hubbl… ]

note:

*Description*: 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 the planet. Uranus is tilted so that its spin axis lies nearly in its orbital plane. This means that only around the time when Uranus's equator is aimed at the Sun (every 42 years) do the orbits of its satellites lie edge-on to the Sun, allowing their shadows to strike the planet, producing solar eclipses on the planet.
