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 ...
What’s known about Uranus could be off the mark. An unusual cosmic occurrence during the Voyager 2 spacecraft’s 1986 flyby might have skewed how scientists characterized the ice giant, new ...
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, shifting how astronomers understood the mysterious world.
In this map of the Observable Universe, objects appear enlarged to show their shape. From left to right celestial bodies are arranged according to their proximity to the Earth. This horizontal (distance to Earth) scale is logarithmic.
Human-made objects orbiting the Sun, Mercury, Venus, Earth, Mars, and Saturn, including active artificial satellites and space junk; Heliosphere, a bubble in space produced by the solar wind Heliosheath. Heliopause; Hydrogen wall, a pile up of hydrogen from the interstellar medium
Scientists may have explained a mystery that has puzzled us about Uranus for decades. Researchers believe that data that appeared not to make sense was collected by a powerful solar storm. In 1986 ...
For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the gas giants. Uranus's atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons.
