HD 197036 is a single star in the northern constellation Cygnus. It has an absolute magnitude of −1.15[1] and an apparent magnitude of 6.61,[2] below the max naked eye visibility. Located 1,310 light years away, it is approaching Earth with a heliocentric radial velocity of Template:Val.[3]

HD 197036 is a bluish white subgiant star of the spectral type B5IV, and has an angular diameter of Template:Val.[4] This yields a radius of Template:Val[5] at its estimated distance. At present it has 4.21 times the mass of the Sun[6] and shines at 379 times the luminosity of the Sun[1] from its photosphere at an effective temperature of 13,399 K,[7] giving it a bluish white hue. Like many hot stars, it spins rapidly with a projected rotational velocity of 135 km/s−1[8] and has a near solar metallicity.[6]
