List of minor planet discoverers

This is a list of all astronomers who are credited by the Minor Planet Center (MPC) with the discovery of one or several minor planets.[1] A second table lists all institutional discoverers of minor planets such as observatories and surveys (see § Discovering dedicated institutions). As of March 2018, the MPC credits a total of 514,567 numbered minor planets to 1014 astronomers and 234 institutional discoverers (e.g. observatories, telescopes and surveys), respectively.

For a detailed description of the table's content, see § Notes.
