  2. Exploration of Uranus - Wikipedia

    en.wikipedia.org/wiki/Exploration_of_Uranus

    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 ...

  3. Uranus - Wikipedia

    en.wikipedia.org/wiki/Uranus

    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 .

  4. Atmospheric escape - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_escape

    One classical thermal escape mechanism is Jeans escape, [1] named after British astronomer Sir James Jeans, who first described this process of atmospheric loss. [2] In a quantity of gas, the average velocity of any one molecule is measured by the gas's temperature, but the velocities of individual molecules change as they collide with one another, gaining and losing kinetic energy.

    Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings. Images of which were captured in rich detail last year by the James Webb Space Telescope .

  8. VSOP model - Wikipedia

    en.wikipedia.org/wiki/VSOP_model

    The same precision is ensured for Jupiter and Saturn over 2,000 years and for Uranus and Neptune over 6,000 years before and after J2000. [1] This, together with its free availability has resulted in VSOP87 being widely used for planetary calculations; for example, it is used in Celestia and Orbiter.

  9. Voyager 2 - Wikipedia

    en.wikipedia.org/wiki/Voyager_2

    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.
