Dwarf spheroidal galaxy NGC 147 is a member of the Local Group of galaxies. It is a satellite of the Andromeda Galaxy. It forms a physical pair with the nearby galaxy NGC 185, another remote satellite of Andromeda Galaxy. It was discovered by John Herschel in September 1829. Visually it is both fainter and slightly larger than NGC 185, but both galaxies are visible in small telescopes. NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light years in diameter and approximately 60 million light years distant. ...

The membership of NGC 147 in the Local Group was confirmed by Walter Baade in 1944 when he was able to resolve the galaxy into individual stars with the 100 inch telescope at Mount Wilson near Los Angeles. The distance to NGC 147 has been estimated to be at 2.4 million light years.
