space velocity
subject			fact

space velocity	has definition A star's total velocity with respect to the local standard of rest. This is the combination of the star's U, V, and W velocities: space velocity = sqrt (U2 + V2 + W2). For example, the Sun (U = -9, V = +12, W = +7) has a space velocity of 17 kilometers per second.
	is a kind of galactic velocity component
velocity	has base unit length per unit time
quantity	has unit
number	has value

Kinds of space velocity :

• solar velocity (2 facts) - Velocity of the Sun (19.4 km sin the direction l^II = 51°, b^II = 23°) with respect to the local standard of rest.
