Who discovered 40 Eridani A?
The primary star of the system, designated 40 Eridani A, formally named Keid from the traditional name for the system, is easily visible to the naked eye. It is orbited by a binary pair whose two components are designated 40 Eridani B and C, and which were discovered on January 31, 1783, by William Herschel.
