List of numbered comets
This is a list of periodic comets that were numbered by the Minor Planet Center after having been observed on at least two occasions.[1] Their orbital periods vary from 3.2 to 366 years. As of December 2020 there are 409 numbered comets (1P–409P), most of them being members of the Jupiter-family (JFC). There are also 28 Encke-type comets (ETCs), 14 Halley-type comets (HTCs), 5 Chiron-type comets (CTCs), and one long-period comet (i.e. 153P). About a third of these bodies are also near-Earth comets (NECs). In addition, 8 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.
Occasionally, comets will break up into multiple chunks, as volatiles coming off the comet and rotational forces may cause it to break into two or more pieces. An extreme example of this is 73P/Schwassmann–Wachmann, which broke into over 50 pieces during its 1995 perihelion.
For a larger list of periodic Jupiter-family and Halley-type comets including unnumbered bodies, see list of periodic comets.

73P/Schwassmann–Wachmann
In 1995, comet 73P/Schwassmann–Wachmann, broke up into several pieces and as of its last perihelion date, the pieces numbered at least 67 with 73P/Schwassmann–Wachmann C as the presumed original nucleus. Because of the enormous number, the pieces of it have been compiled into a separate list.[2]
This is a list of 73P/Schwassmann–Wachmann (68 entries) with all its cometary fragments listed at JPL's SBDB (see list).
