Overview
This is a list of periodic comets that were numbered by the Minor Planet Center after having been observed on at least two occasions. Their orbital periods vary from 3.2 to 366 years. As of August 2026, there are 516 numbered comets (1P–516P). There are 442 Jupiter-family comets (JFCs), 45 Encke-type comets (ETCs), 15 Halley-type comets (HTCs), five Chiron-type comets (CTCs), and one long-period comet. 79 bodies are also near-Earth comets (NECs). In addition, nine numbered comets are principally classified as minor planets – six main-belt comets, two centaurs (CEN), and one Apollo asteroid – and display characteristics of both an asteroid and a comet.
