HD 167714 eller HR 6837 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Oktanten. Den har en skenbar magnitud av ca 5,95^[2] och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 3 på ca 9,08 mas,^[1] beräknas den befinna sig på ett avstånd på ca 359 ljusår (110 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -14 km/s.^[5]

Egenskaper

HD 167714 är en orange till röd jättestjärna av spektralklass K2 III,^[3] som befinner sig på den röda jättegrenen^[14] och genererar energi genom kärnfusion av helium i dess kärna. Den har en massa som är ca 1,4^[7] solmassa, en radie som är ca 12,3^[8] solradier och utsänder energi från dess fotosfär motsvarande ca 65 gånger solen^[7] vid en effektiv temperatur av ca 4 700 K.^[8]
