323P/SOHO
Sign in to save323P/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.

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.
== Observational history == The comet was first noticed by Rainer Kracht in images obtained on 12 March 2004, getting the name C/2004 E2. In 2006 it was published that a very faint comet was visible in SOHO images obtained on 12 December 1999. R. Kracht identified these two objects as being the same comet that had been observed by SOHO on 30 May 2008, a link subsequently confirmed by Brian G. Marsden.
