NotesA barred spiral galaxy more than 160,000 light years in diameter, IC 4572 is the largest and most massive member of a small galaxy group in Corona Borealis. As seen from Earth, this spiral and its fellow galaxies fall within the arc of stars forming the constellation of the Northern Crown.

IC 4572 is the largest of a small group of galaxies in central Corona Borealis. Also visible in this image, directly to the south of IC 4572, is PGC 3851695, a small spiral galaxy that actually lies slightly closer to the Milky Way. In the extreme west (right) of the image is another small and faint galaxy, PGC 4118703, which is also part of the same group. Imagery provided by Aladin sky atlas
