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 ...
The International Designator, also known as COSPAR ID, is an international identifier assigned to artificial objects in space. [1] It consists of the launch year, a three-digit incrementing launch number of that year [n 1] and up to a three-letter code representing the sequential identifier of a piece in a launch.
