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 astronomer William Herschel on April 15, 1784. [5] It is a member of the Virgo Cluster. [6]
Physical characteristics
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]
