El [[Minor Planet Center|MPC]] acredita més de 1000 astrònoms professionals i aficionats com descobridors de planetes menors. Molts d'ells han descobert només uns pocs planetes menors o fins i tot només han sigut co-descobridors d'un de sol. D'altra banda un descobridor no necessita ser un ésser humà. Hi ha al voltant de 300 programes de recerca i observatoris acreditats com descobridors. Entre ells, un petit grup de programes de recerca dels Estats Units en realitat representen la major part de tots els descobriments realitzats fins al moment (veure gràfic de la part inferior). A mesura que el total de planetes menors numerats està creixent per milers sobre una base mensual, totes les xifres estadístiques estan canviant constantment.
The MPC credits more than 1000 professional and amateur astronomers as [[discoverers of minor planets]]. Many of them have discovered only a few minor planets or even just co-discovered a single one. Moreover a discoverer does not need to be a human being. There are about 300 programs, surveys and observatories [[List of minor planet discoverers#Discovering dedicated institutions|credited as discoverers]]. Among these, a small group of U.S. programs and surveys actually account for most of all discoveries made so far ''(see pie chart)''. As the total of numbered minor planets is growing by the thousands on a monthly basis, all statistical figures are constantly changing. Note that the MPC summarizes the total of discoveries somewhat differently (typically by distinct group of discoverers), for example, bodies discovered in the Palomar–Leiden Survey are directly credited to the trio of astronomers as displayed in the above table.
