The minimum temperature amongst the atmosphere on Uranus is -224c. One day on Uranus takes about 17 hours which is the time it takes for Uranus to rotate on its axis once. In addition, the axis of the planets magnetic field is substantially tipped relative to the rotation axis and offset from the planets centre. [3] Even though Uranus is the third largest planet in our solar system and four hundred times the size of Earth, the planet is not readily visible to the naked eye. Its magnetic field lines are twisted by Uranus sideways rotation into a long corkscrew shape. From numerous pieces of debris that formed as a result of those impacts, only a few particles survived, in stable zones corresponding to the locations of the present rings. NASA's Voyager 2 is the only spacecraft in the history of spaceflight that has made a close approach to Uranus. Winds on Uranus can travel as fast as 560 miles per hour. The lander cleared enough dust from one solar panel to keep its seismometer on through the summer, allowing scientists to study three big quakes.

Uranus orbits our Sun, a star, and is the seventh planet from the Sun at a distance of about 1.8 billion miles (2.9 billion kilometers). The correct pronunciation of Uranus is [YUR-uh-nus] not [Your Anus]. In fact, when Flamsteed first observed it, he cataloged it as 34 Tauri, believing it to be a star in the Taurus constellation. Earth-based attempts to measure a property as basic as the planetary rotation period had produced widely differing values, ranging from 24 to 13 hours, until Voyager 2 finally established a 17.24-hour rotation period for the Uranian interior. At present, astronomers have confirmed the existence of 27 natural satellites. The clouds in Uranuss upper atmosphere are made up largely of hydrogen sulfide, which is what makes rotten eggs stink.

So if you were weighed on Uranus, you would weighonly 0.89% of your actual weight on Earth. Unlike most planets, the axis of Uranus lies almost parallel to its orbital plane, which means that the planet spins nearly on its side, its poles taking turns pointing toward the Sun as the planet travels in its orbit. The matter in the rings may once have been part of a moon (or moons) that was shattered by high-speed impacts. All of Uranus's 27 moons are named after characters from William, Uranus is the coldest planet in the solar system, even though, Uranus gets about 1/400th of the sunlight that, Sometimes one pole of Uranus faces directly toward the.
