In page Vega:

"

In the galactic coordinate system, the space velocity components of Vega are (U, V, W) = (−16.1±0.3, −6.3±0.8, −7.7±0.3) km/s, for a net space velocity of 19 km/s.[3] The radial component of this velocity—in the direction of the Sun—is −13.9 km/s, while the transverse velocity is 12.9 km/s.[citation needed] Although Vega is at present only the fifth-brightest star in the night sky, the star is slowly brightening as proper motion causes it to approach the Sun.[4] Vega will make its closest approach in an estimated 264,000 years at a perihelion distance of 13.2 ly (4.04 pc).[5]
