Right Drag with your mouse after you run the links above that display planetary orbits to get a good sense of their 3-dimensional aspects.
Are you unfamiliar with our 1.6.x and 1.4.1 links? For an explanation click here.
A gas giant, Uranus has no solid or liquid "surface". So its "visible surface" is really the top of its complex cloud system! As no spacecraft has yet sent back pictures from within or directly above the planet's awesome cloud layers, artists' depictions will have to suffice for now.
The following will help you enjoy this page's 1.6.x and 1.4.1 links that run events directly in CELESTIA. If you're new to the program, these tips will also help you learn to use it.
You'll find more information about many of CELESTIA's controls on our Learning Center page.
Orbiting on its side,
every 42 years it
points one of its
poles toward us
here on Earth!

URANUS FUN FACTS
Uranus is the furthest planet from Earth that can be seen with the naked eye!
Visible to the naked eye only under the most favorable conditions, Uranus was the first planet discovered using the telescope!
Uranus is the coldest major planet, even though it is closer to the Sun than is Neptune!
QUICK ACCESS LIST
Note: some links are echoed elsewhere on this page and may include descriptive text.
From NOAA's Science on a Sphere site is a 3D Uranus that can be rotated around 2 axes. (When link runs click in the page's right column on "Interactive Sphere".)
Links to interactive features that show Uranus's orbit in 3-D can be found on our Solar System page
NASA-JPL's The Voyager Missions.
Uranus Viewer lets you find the tilt of Uranus & its rings, and the location of its major moons, for any time and date.
Uranus Moon Tracker allows you to generate and download diagrams of the locations of Uranus's major moons and its Epsilon Ring over spans of time.
