HD 41047, eller HR 2131, är en ensam stjärna^[12] i den mellersta delen av stjärnbilden Duvan. Den har en skenbar magnitud av ca 5,52^[2] och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 3 på ca 4,8 mas,^[1] beräknas den befinna sig på ett avstånd på ca 670 ljusår (ca 207 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 19 km/s.^[5]

Egenskaper redigera

HD 41047 är en röd till orange jättestjärna av spektralklass K5 III,^[3] som befinner sig på den röda jättegrenen. Den har en massa som är ca 1,8^[7] solmassor, en radie som är ca 49^[8] solradier och har ca 500 gånger solens utstrålning av energi^[7] från dess fotosfär vid en effektiv temperatur av ca 3 700 K.^[9]
