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