IC 4539 is a type SABb[1] intermediate spiral galaxy located in Corona Borealis. Its redshift is 0.061307,[2] which corresponds IC 4539 to be 845 million light-years from Earth.[3] It has an apparent dimension of 0.40 x 0.4 arcmin, meaning the galaxy is about 95,000 light-years across.[4] IC 4539 was discovered by Stephane Javelle on June 23, 1903, who found it "as faint, small, round with a very brighter middle."[5][6]
