plx = 305.26 [0.7], pmRA = 6768.2 [0.59] and pmDE = 1327.52 [0.68] (HIP2, I/311) => transverse velocity = 107.1 km/s and radvel = +7.58 [0.72] (CRVAD-2,III/254) =>
distance of closest approach = 3.268 pc ; time of closest approach = -2.1 kyr in linear approx.
Space velocities (U,V,W) = (-93.80, -13.41,-50.51) from the data above.
