Linked by strong gravitational forces these two very differently looking galaxies NGC4298 + NGC4302 can be found in the constellation of Coma Berenices.Together they are listed as GX-pair Holm 377 or KPG 332.
The blue one,typed SA(rs)c,is NGC4298 and the yellowish,edged-on one,typed Sc,is labeled NGC4302.Their real distance to our milky-way is about 49mio.light-years and both are belonging to the Virgo Galaxy-Cluster (VGC497).
In 1986 the supernova SN 1986E was observed in NGC4302.
Both are about 12mag. bright and sized 3,2′ × 1,9′ and 5,3′ × 1′.
They were first seen by William Herschel in 1784.
