C/2020 X3 (SOHO), also known as SOHO-4108, is the 3,534th Kreutz sungrazer comet discovered by the Solar and Heliospheric Observatory (SOHO).[3] 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.[5][6]
