Determination of the proper velocities of a space object

by Lewis Carroll
written by Lewis Carroll

Determination of the proper velocities of a space object – It is possible to divide the velocity of a space object into two components. The first is directed towards the observer’s eye, i.e. directly towards or away from it, and the second, perpendicular to the first, is located on the celestial sphere. The second component is measured using an angle, and the first is measured using the Doppler effect, which is based on measuring line changes in the spectrum of the object under study. The generalization of these 2 vectors gives the cosmic body its own velocity.
