HD 72337 är en ensam stjärna i den mellersta delen av stjärnbilden Flygfisken. Den har en skenbar magnitud av ca 5,51^[2] och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 11,4^[1] mas, beräknas den befinna sig på ett avstånd på ca 286 ljusår (ca 88 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 13 km/s.^[5]

Egenskaper

HD 72337 är en vit till blå stjärna i huvudserien av spektralklass A0 V,^[3] även vissa källor anger spektralklass B9 V.^[12] Den har en massa som är ca 2,7^[6] solmassor, en radie som är ca 2,3^[6] solradier och har ca 52 gånger solens utstrålning av energi^[6] från dess fotosfär vid en effektiv temperatur av ca 9 700 K.^[1]
