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]
