Illustrations depict how Uranus' magnetosphere, or protective bubble, was behaving before Voyager 2's arrival (left) and during the spacecraft's flyby (right).
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 .
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 .
The adjectival forms of the names of astronomical bodies are not always easily predictable. Attested adjectival forms of the larger bodies are listed below, along with the two small Martian moons; in some cases they are accompanied by their demonymic equivalents, which denote hypothetical inhabitants of these bodies.
