The component of a object's velocity that is perpendicular to our line of sight.
The breakdown of a star's velocity v into the radial vr and transverse vT components.
The velocity of a star perpendicular to the line of sight.

Transverse Velocity - The part of the orbital speed of a body perpendicular to the Sun between the body and the Sun ...
A star's transverse velocity is easily calculated once its proper motion and its distance are known. At the distance of Barnard's Star (1.8 pc), an angle of 10.3" corresponds to a physical displacement of 0.00009 pc, or about 2.8 billion km.
high-energy nuclei of light elements or by the capture of slow neutrons, followed by beta decay. In nuclear explosions, transuranic elements may be produced by numerous successive captures of neutrons by uranium nuclei. [DC99]
Also known as transverse velocity. telescope temperature (Celsius) temperature (color) temperature (effective) temperature (Fahrenheit) temperature (Kelvin) temperature (kinetic) terrestrial planet Mercury, Venus, ...
For Barnard's star this works out to 90 km/s; including the radial velocity of 111 km/s (which is at right angles to the transverse velocity) gives a true motion of 142 km/s.
A star's proper motion depends on its actual transverse velocity and inversely with its distance from us.
Proper motion: Apparent angular motion of a star on the celestial sphere, usually measured in seconds of arc per year. A star's transverse velocity, i.e.
contribution to the red shift causes errors in determination of the distance of massive quasars (making them appear further away) thus giving a very large value for calculated emitted energy. This also results is a calculated transverse velocity ...
reflect the relativistic Doppler dilation and boost effects. If we consider the projected separation between a stationary core and a blob moving away from it at a rate c b at an angle q to our line of sight, the apparent transverse velocity will be ...
