Uranus is surrounded by its four main rings and 10 of its 27 known moons in this color view that uses data taken by the Hubble Space Telescope in 1998. A study with new modeling shows that four of Uranus' large moons likely contain internal oceans. Image credit: NASA/JPL/STScI. ...
Venus takes about 225 Earth days to orbit the Sun and rotates at the incredibly slow rate of once every 243 days - and in a clockwise direction (as seen from looking down on the Suns north pole). Only Uranus (which almost spins on its side) also has a clockwise spin. Because of the...
Voyager 2 flew by Uranus in 1986, giving us our only up-close look at the planet – but unusual space weather just before the craft arrived has given us a misleading idea about the planet’s magnetic field
(The thumbnail image for this article was created using a combination of the Stellarium free planetarium software, along with images of Uranus and Neptune from NASA. The planets are shown immensely exaggerated from their actual size in our night sky.) ...

INTERVIEWATNASAABOUTPLANETX Watch the Video In the early 1990's, calculations by the United States Naval Observatory have confirmed the orbital perturbation exhibited by Uranus and Neptune, whichDr. Thomas C Van Flandern, an astronomer at the observatory, says could be explained by "a single undi...
“The most mundane explanation is that it’s kind of a smaller version of Uranus and Neptune, and probably one of the cores that participated in the formation process of those planets.” The super-Earth hypothesis is perhaps the one that gets the most support among Plan...
