IC 289 is a planetary nebula in the constellation Cassiopeia.[3] It was discovered by Lewis Swift in early September 1888. It lies close to the 10th magnitude star BD +60° 0631. N.J. Martin described IC 289 as "A nice, faint round planet like planetary nebula. The uniform oval disc shows some irregularity in brightness but is not obviously brighter at the edge."[citation needed]
