Planetary Comets is a scientific exploration of the fascinating world of comets in our solar system. We will explore the origins and composition of comets, their behavior and impact on our planet, and the potential for future exploration. We will also delve into the history of cometary research,
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 March 2026, there are 514 numbered comets (1P–513P). There are 441 Jupiter-family comets (JFCs), 50 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, eight numbered comets are principally classified as minor planets – five main-belt comets, two centaurs (CEN), and one Apollo asteroid – and display characteristics of both an asteroid and a comet.
