NGC 4469 is a nearly edge-on spiral galaxy located about 55 million light-years away in the constellation of Virgo. It is also classified as a LINER galaxy. NGC 4469 was discovered by German-British astronomer William Herschel on April 15, 1784. It is a member of the Virgo Cluster.

Physical characteristics

HST image of NGC 4469 showing filaments of dust and a distinct peanut shaped bulge.

NGC 4469 has an X or peanut-shaped bulge, betraying the presence of a bar which generates such structures. NGC 4469 may also have an axisymmetric structure.

Dust Lanes

NGC 4469 has dust lanes that cross the Earth's line of sight.
