Uranus is the "tipped over" planet!  As if "lying on its side," it seems to "roll along" in its orbit!  (1.6.x)   (1.4.1)

Uranus, the seventh planet from the Sun, points one of its poles toward the Sun about every 42 years!  (1.6.x)  (1.4.1)

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.

CLOUDTOP VIEW

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.

CELES-TIPS

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.

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!

URANUS INTERACTIVES

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.
