... Since a star’s brightness varies as√ the inverse square of the distance, the distance would have to decrease by a factor of 15.85 = 3.981. (I.e., 3.9812 = 15.85.) Since Barnard’s star is now at 5.9 ly, we would have to move it to 5.9/3.981 = 1.48 ly. Barnard’s star is actually moving towards us at 1 ...

R136a1
RMC 136a1 (usually abbreviated to R136a1) is a Wolf-Rayet star located at the center of R136, the central condensation of stars of the large NGC 2070 open cluster in the Tarantula Nebula. It lies at a distance of about 50 kiloparsecs (163,000 light-years) in the Large Magellanic Cloud. It has the highest mass and luminosity of any known star, at 265 M☉ and 8.7 million L☉, and also one of the hottest at over 50,000 K.
