Movement of stars

[Space Traveller]

Hi All,

I'm new to the forum and have always been fascinated with the heavens going back to school days.

My question is this, when we analyze the light coming from Star A & Star B in the attached sketch, we find that they are both Red-Shifted.  The question is, in the simplest form, which direction are these stars moving in relationship to earth?

I want to make it quite clear this is not a trick question.

Best Rgds,

Both are moving away from the earth. Regards Andrew

My take on it (uneducated oik that I am!) is that Star A is moving towards the left side of the screen and Star B towards the right.

If both are red-shifted then as Andrew said both are moving away from Earth. The respective red shift ratio would give an indication of their recessional velocities.
