UGC 3855, also known as PGC 21067 or sometimes as the Modest galaxy, is a spiral galaxy located around 40 Mpc from Earth in the constellation of Lynx.[1][2] It is a relatively old galaxy with a stellar population around 10.6 billion years old. It also has a low rate of star formation of about 0.2 solar masses per year.[3]
It was the host galaxy to a supernova known as SN 2021agco, the closest ultra-stripped supernova discovered.[3]
