It was not detected again until the Hubble Space Telescope observed it in 1997. [7] [9] Cordelia takes its name from the youngest daughter of Lear in William Shakespeare's King Lear. It is also designated Uranus VI. [10] Other than its orbit, [4] size of 50 × 36 km, [5] and geometric albedo of 0.06, [7] virtually nothing is known about it.
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 ...
Instead, proper or mean orbital elements are used to describe the long-term orbits of irregular moons more accurately, since these are calculated by averaging out the perturbed orbit over a long period of time. [7]: 4 Over an 800-year time span from 1600 to 2400, S/2023 U 1's average semi-major axis or orbital distance from Uranus is 7.98 ...
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 1781, German-born British astronomer William Herschel made Uranus the first planet discovered with the aid of a telescope. This frigid planet, our solar system's third largest, remains a bit of ...
Because during their formation Uranus and Neptune incorporated their material as either ice or gas trapped in water ice, the term ice giant came into use. [ 2 ] [ 4 ] In the early 1970s, the terminology became popular in the science fiction community, e.g., Bova (1971), [ 5 ] but the earliest scientific usage of the terminology was likely by ...
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 ...
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 .
