322P/SOHO is the first periodic comet to be discovered using the automated telescopes of the Solar and Heliospheric Observatory (SOHO) spacecraft, and second to be given a numbered designation, after 321P/SOHO. At perihelion, it is six times closer to the Sun than the planet Mercury.

323P/SOHO is a periodic comet with an orbital period of 4.15 years discovered in images obtained by the Solar and Heliospheric Observatory (SOHO). It is considered to be a sungrazing comet due to its perihelion being very close to the Sun. 323P/SOHO has the smallest perihelion of all numbered comets.
