    27°N = Gaia DR3 3320184202856435840 = EGGR 290   =>  19 Kyr 

      

    56°N = Gaia DR3 5853498713190525696 = Proxima Cen =>  27 Kyr     perihelion of 26.622 kyr (90% CI 26.580–26.653 kyr).

    which is not surprising because Proxima Centauri’s orbital period of 547+66 −40 kyr

     

    3°N   = Gaia DR3 5544743925212648320 = UPM J0812-3529 => 29 Kyr   

    then it will pass just 0.11 pc from the Sun in 29 kyr

     for example, the star would come about 0.008 pc (7%) closer.

     

    53°N = Gaia DR3 1926461164913660160 = Ross 248 =>  36 Kyr
