2 2 2 ▁ ± ▁ 7 ▁light - year s ▁away ▁with ▁an ▁apparent ▁magnitude ▁of ▁ 4 . 3 9 , ▁HD ▁ 6 6 1 4 1 ▁is ▁ 6 . 8 ▁billion ▁years ▁old ▁and ▁has ▁evol ved ▁into ▁an ▁orange ▁giant ▁of ▁spectral ▁type ▁K 2 III ▁with ▁a ▁diameter ▁around ▁ 2 2 ▁times ▁that ▁of ▁the ▁Sun , ▁and ▁we igh ing ▁ 1 . 1 ▁solar ▁masses . ▁It ▁is ▁ 1 7 4 ▁times ▁as ▁l umin ous ▁as ▁the ▁Sun , ▁with ▁an ▁absolute ▁magnitude ▁of ▁− 0 . 1 5 . ▁HD ▁ 6 6 1 4 1 ▁was ▁mistaken ly ▁named ▁ 1 3 ▁Pu pp is , ▁as ▁its ▁cel est ial ▁coordinates ▁were ▁recorded ▁incorrectly ▁when ▁catalog ued ▁and ▁hence ▁mistaken ly ▁thought ▁to ▁be ▁in ▁the ▁const ell ation ▁of ▁Pu pp is ; ▁B ode ▁gave ▁it ▁the ▁name ▁L ambda ▁Can is ▁Minor is , ▁which ▁is ▁now ▁ob sole te . ▁The ▁orange ▁giant ▁is ▁orb ited ▁by ▁a ▁planet , ▁HD ▁ 6 6 1 4 1 b , ▁which ▁was ▁detected ▁in ▁ 2 0 1 2 ▁by ▁meas uring ▁the ▁star ' s ▁radial ▁velocity . ▁The ▁planet ▁has ▁a ▁mass ▁around ▁ 6 ▁times ▁that ▁of ▁Jup iter ▁and ▁a ▁period ▁of ▁ 4 8 0 ▁days . ▁ ▁A ▁red ▁giant ▁of ▁spectral ▁type ▁M 4 III , ▁BC ▁Can is ▁Minor is ▁lies ▁around ▁ ▁distant ▁from ▁the ▁Sol
