NGC 4469 is a nearly edge-on spiral galaxy ^[2] located about 55 million light-years away ^[3] in the constellation of Virgo. ^[4] It is also classified as a LINER galaxy. ^[3] NGC 4469 was discovered by German-British astronomer William Herschel on April 15, 1784. ^[5] It is a member of the Virgo Cluster. ^[6]

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. ^{[2] [7]} NGC 4469 may also have an axisymmetric structure. ^[8]

Dust Lanes

NGC 4469 has dust lanes that cross the Earth's line of sight. ^[6]
