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 ...
Neptune, which is Uranus's near twin in size and composition, radiates 2.61 times as much energy into space as it receives from the Sun, [23] but Uranus radiates hardly any excess heat at all. The total power radiated by Uranus in the far infrared (i.e. heat) part of the spectrum is 1.06 ± 0.08 times the solar energy absorbed in its atmosphere .
The length of a day on Uranus as measured by Voyager 2 is 17 hours, 14 minutes. [49] Uranus was shown to have a magnetic field that was misaligned with its rotational axis, unlike other planets that had been visited to that point, [50] [53] and a helix-shaped magnetic tail stretching 10 million kilometers (6 million miles) away from the Sun. [50]
Illustrations depict how Uranus' magnetosphere, or protective bubble, was behaving before Voyager 2's arrival (left) and during the spacecraft's flyby (right).
In 1986, Nasa’s Voyager 2 flew by the seventh planet in the Solar System, providing scientists with their first and only glimpse of Uranus, and shaping their understanding of it since.
But long before that, Voyager 2 stopped by Uranus, coming within 50,600 miles of Uranus' cloudtops. ... Voyager 2's flyby may have taken place at the same time that some unusual space weather was ...
Typically, the stated rotation period for a giant planet (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as determined from the rotation of the planet's magnetic field. For objects that are not spherically symmetrical, the rotation period is, in general, not fixed, even in the absence of gravitational or tidal forces.
NASA scientists say Uranus' rings have only been captured by two other cameras. They were first scoped out by the Voyager 2 spacecraft as it flew past in 1986. Later, the Kec
