The brighter component, γ2 Delphini, has an orange hue with a class of K1IV. Being the more massive star of the pair, it is the more evolved star and is currently on the subgiant branch. It has double the mass of the Sun but has expanded to over eight times the Sun's radius. The star is radiating 33 times the luminosity of the Sun at 4,798 K. It is spinning with a projected rotational velocity of 3.6 km/s. The star displays a radial acceleration with a periodicity of 1.44 years, which may be the effect of an orbiting companion.
