The transverse velocity = 21.65 km/s and radvel = -31.0 [0.2] (PCRV,
III/252
) =>
distance of closest approach = 1.921 pc ; time of closest approach = +71.1 kyr in linear approx.
period of the transit within 3 pc from the Sun : +11.5 --> +130.7 kyr
within 2 pc : +60.2 --> +82.0 kyr
Space velocities (U,V,W) = (+17.73,+5.05,-33.02) from the data above.
