WHAT DOES PROPER MOTION MEAN IN ENGLISH?

proper motion

Proper motion

The proper motion of a star is its rate of angular change in position over time, as observed from the center of mass of the Solar System. It is measured in seconds of arc per year, arcsec/yr, where 3600 arcseconds equal one degree. This contrasts with radial velocity, which is the time rate of change in distance toward or away from the viewer, usually measured by Doppler shift of received radiation. The proper motion is not entirely "proper" because it includes a component due to the motion of the solar system itself. Due to the finite speed of light the instantaneous velocities of distant stars cannot be observed; the observed proper motion reflects the velocity of a star at the time the light was emitted from that source. Relation between proper motion and velocity components of an object. At emission, the object was at distance d from the Sun, and moved at angular rate μ radian/s, that is, μ = vt / d with vt = the component of velocity transverse to line of sight from the Sun.

Definition of proper motion in the English dictionary

The definition of proper motion in the dictionary is the very small continuous change in the direction of motion of a star relative to the sun. It is determined from its radial and tangential motion.
