Size comparison of Earth and Uranus. Uranus's mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune's at roughly four times that of Earth. A resulting density of 1.27 g/cm 3 makes Uranus the second least dense planet, after Saturn.
One year on Uranus lasts around 84 Earth years, and for about a quarter of the Uranian year, the sun shines directly over one of the planet’s poles, which means the other half of Uranus ...
Uranus has been the butt of a lot of jokes (stop giggling). And it doesn't help that it's huge — roughly four times the size of Earth — or gassy with an atmosphere comprised partly of methane.
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, ... Days before the flyby, an intense solar wind event was released from the sun ...
Among Uranus's five major moons, Ariel is the second closest to the planet, orbiting at the distance of about 190,000 km. [f] Its orbit has a small eccentricity and is inclined very little relative to the equator of Uranus. [3] Its orbital period is around 2.5 Earth days, coincident with its rotational period.
Miranda, also designated Uranus V, is the smallest and innermost of Uranus's five round satellites. It was discovered by Gerard Kuiper on 16 February 1948 at McDonald Observatory in Texas, and named after Miranda from William Shakespeare's play The Tempest. [9] Like the other large moons of Uranus, Miranda orbits close to its planet's ...
This week, revisit what you know about Uranus, explore the far side of the moon, rediscover the famed fossil known as Lucy, and meet an otherworldly sea creature.
Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours and 14 minutes. Uranus is distinguished by the fact that it is tipped on ...
