NGC 5170 is edge-on spiral galaxy about 96 million light-years away in the constellation
Virgo. It has an apparent size of 9.9 x 1.2 arc minutes and shines at a mag 12.4. A
prominent broad dark lane with mottled detail can be seen running about three quarters
of the length of the galaxy - most prominent against the bright core area. That core area
shows the yellowish hue of old stars commonly found there, with the bluer outer arm
regions showing the hue of hot young stars.
