Astronomy 10: Introduction to General Astronomy Instructor: Tony
... When we measure velocities of stars using Doppler shifts, it can only measure the radial velocity (that is, the velocity directly toward or away form us). In general, the orbit can be at an angle from us, so that the true orbital velocity is equal or greater than what we measure. In turn the inferre ...
