NGC 4638 is an edge-on lenticular galaxy[2] located about 50 million light-years away[3] in the constellation Virgo.[4] NGC 4638 was discovered by astronomer William Herschel on March 15, 1784.[5] The galaxy is a member of the Virgo Cluster.[6][7]
Structure
[edit | edit source]At the center of NGC 4638, there is a small bulge. There is also an edge-on disk and a diffuse, boxy halo. The shallow surface brightness gradient of the halo is characteristic of a large spheroidal galaxy. This means that NGC 4638 has properties of both S0 and Sph galaxies.[8]
