HD 218108 är en vit till blå stjärna i huvudserien av spektralklass A6 Vn, med breda eller diffusa absorptionslinjer på grund av snabb rotation (projicerad rotationshastighet 194 km/s). Den har en massa som är lika med ca 1,8 solmassa, en radie som är ca 2 solradier och utsänder energi från dess fotosfär motsvarande ca 15 gånger solen vid en effektiv temperatur av ca 8200 K. Stjärnan har metallicitet ungefär samma som solens.
