IC 3447 (or PGC 165209) is a type Sc[1] barred spiral galaxy[citation needed] located in the constellation Virgo. It has a redshift of 0.092479,[2] which means IC 3447 is 1.27 billion light-years from Earth,[3] making it one of the furthest objects in the Index Catalogue.[4] The galaxy has apparent dimensions of 0.30 x 0.3 arcmin, which means IC 3447 is 111,000 light-years across.[5] It was discovered by Royal Harwood Frost on May 10, 1904.[6][7]
