C/2020 X3 (SOHO), also known as SOHO-4108, is the 3,534th Kreutz sungrazer comet discovered by the Solar and Heliospheric Observatory (SOHO). It is notable for appearing during the total solar eclipse of 14 December 2020. Due to its small size, only about a few meters across, it completely disintegrated upon perihelion only 22 hours after being discovered.
