Biography
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. A second table lists all institutional discoverers of minor planets such as observatories and surveys (see § Discovering dedicated institutions). As of May 2019, the MPC credits a total of 541,128 numbered minor planets to 1020 astronomers and 235 institutional discoverers (e.g. observatories, telescopes and surveys), respectively.
For how a discovery is made and a detailed description of the table, see observations of small Solar System bodies and § Notes, respectively.
