Lets do a quick calculation, and neglect all aspects of proper stellar kinematics -- Our sun has traveled quite some distance itself during the 70000 years, I don&#x27;t properly described that motion itself, so take everything with a grain of salt: Lets call the speed difference of the star with respect to our sun `Δv` Δv = 20 [ly] / 70 000 [y] = 0.000285714 [ly/y] Now, lets convert the unit `ly/y` into a unit that we can relate to, to get a grasp on it: 1ly = 63241.08AU[1]. Δv = 0.000285714 [ly/y] = 18.0688 [AU/y] 18 AU is about the perihelion of…</p><p><a href="https://hackerpaper.kaipfister.de/p/1411.3572/">Paper and discussion history</a>.
