IC 4481 is a type SBbc[1] barred spiral galaxy located in Boötes. Its redshift is 0.110727, meaning IC 4481 is located 1.49 billion light-years away from Earth.[2] It is one of the furthest objects in the Index Catalogue[3] and has an apparent dimension of 0.30 x 0.2 arcmin.[4][5] IC 4481 was discovered on May 10, 1904, by Royal Harwood Frost, who found it "faint, very small, round and diffuse".[6]
