Very blue point source -- Is it moving towards us?

This one looks a lot more blue than most stars. Could it be moving towards, due to blueshift? (Does that happen?) Or is it a quasar? Very equal brightnesses in all 3 bands.


It could be a blue star, or perhaps a quasar. In this view,
you can see two nearby blue sources with SDSS spectra: one is a high-mass (hot-burning) A star, the other a quasar at redshift 2.9.

High-velocity stars move at about 1000 km/s (or that ballpark), so produce only a tiny bit of blueshift.


Thanks for the explanation Dustin. This one looks pretty similar—maybe slightly more blue. Probably it’s also either a blue star or a quasar?
