what would be the best star to move the earth to?
reading Cixin Liu's, "the wandering earth" today, which narrates a quest to move the earth from its orbit to our sun to one around proxima centauri via massive fusion thrusters. my thought after reading the very first page of the story was "obviously proxima centauri would be no good because that is a flare star". I haven't gotten to the point of modeling orbits or reading papers on this, but my guess is that alpha centauri a and b are also too close together and share too elliptical an orbit to stably place the earth around either or both at an appropriate distance. looking down the list of nearest stars on wikipedia, Lalande 21185 is the closest singlet non-flare stare, so i land on that as a tentative answer, but am not sure how much it's been studied. better known stars like eridani and tau ceti seem somewhat viable though a bit further, but with obvious drawbacks compared to our own star. does anyone else have thoughts on this?
