NGC 4469 is a nearly edge-onspiral galaxy[2] located about 55 millionlight-years away[3] in theconstellation ofVirgo.[4] It is also classified as aLINER galaxy.[3] NGC 4469 was discovered by German-British astronomerWilliam Herschel on April 15, 1784.[5] It is a member of theVirgo Cluster.[6]

Physical characteristics

[edit]
HST image of NGC 4469 showing filaments of dust and a distinct peanut shapedbulge.

NGC 4469 has an X or peanut-shapedbulge, 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 theEarth's line of sight.[6]
