jude_rookThis star is also known as Gliese 892 and HD 219134 (among others -- there have been quite a few star catalogues compiled over the years.) Located 21 light years away in Cassiopeia, it’s a K3V star that seems to have a metallicity around the same as Sol’s, but that flares up from time to time. Flare stars are usually M class red dwarfs, but they do occur among the K stars as well. Any settlers might need artificial protection, or the natural kind that comes with a thick atmosphere or powerful planetary magnetic field. I didn’t find any info on how old it is.
ETA: Bryden et al give it an age of 5.5 billion years and a metallicity of 3.5 times that of Sol.
Just for kicks, here are the other catalogue numbers for this particular star, as listed in the Internet Stellar Database: Bonner Durchmusterung (BD) +56°2966, Luyten Half-Second (LHS) 71, Hipparcos Input Catalog (HIC) 114622, Smithsonian Astrophysical Observatory (SAO) 35236, Fifth Fundamental Catalogue (FK5) 875, New Suspected Variable (NSV) 14458. The HR number is from the Hoffleit Bright Star Catalogue and the HD number is from the Henry Draper catalogue. Some of these catalogues are obsolete, but there are times when the old designations continue to cling to stars. When I was a kid reading up on the stars near Sol, this one was always cited as HR 8832, so that’s how I think of it.
