HD 196885 is a 6th magnitude binary star in the constellation Delphinus. According to its parallax of 29.83 milliarcseconds, it is located at a distance of 109 light years from Earth. In 2004, a planet was announced to be orbiting the star in a 386-day orbit. Follow-up work published in 2008 did not confirm the original candidate but instead found evidence of a planet in a 1349-day orbit.

The star BD+10 4351B, located 192 arcseconds away from HD 196885 is located at the same distance and may be a physically bound companion star, in which case HD 196885 is a triple system. If it is bound, then the separation is at least 6600 AU (the separation along the line-of-sight is unknown, so this value represents a lower limit on the true separation).
HD 196885 A
HD 196885 A is an F6IV star. It has a mass of 1.33 solar masses and a radius of 1.79 times that of our Sun.
HD 196885 B
HD 196885 B is a red dwarf star separated by 0.7 arcseconds from the primary star. At a distance of 112 light years, this corresponds to a separation of 24 AU between the stars. Since the separation along the line-of-sight is unknown, this represents a lower limit on the true separation.
