Three-decade old data may have just led scientists to make a new discovery about Uranus.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
This discovery was the first known observation of satellites orbiting another planet. [85] ... Uranus, to be observed in modern times in 1781.
