HD 1032(HR 47) is a solitary[14]starin the southerncircumpolar constellationOctans.It is faintly visible to thenaked eyewith anapparent magnitudeof 5.77[2]and is estimated to be 850light yearsaway from theSolar Systembased onparallaxmeasure.[1]However, it is receding with a heliocentricradial velocityof4km/s.
HD 1032 is anasymptotic giant branch[3]star with astellar classificationof M0/1 III[4]— intermediate between a M0 and M1giant star.It has 111% themass of the Sun[8]and an enlargedradiusof95.54R☉[9]as a result of itsevolved state.It radiates at 1,461 times theluminosity of the Sun[10]from itsphotosphereat aneffective temperatureof3,838K,[11]giving a red hue. HD 1032 is slightly metal deficient with anironabundance 83% that of theSun.[8]
This is a suspectedvariable starthat fluctuates betweenmagnitudes5.82 and 5.88 in theHipparcos passband.[5]
