HD 81040 b
HD 81040 b is a massive, gas giant planet that orbits the star HD 81040. The period is just over 1000 days. It has a semimajor axis of about 1.95 AU. The orbit is quite eccentric, at a little over 0.5 in value. Astrometry of HD 81040 has determined an orbital inclination of either 73° or 107°, depending on whether the solution is prograde or retrograde. This, combined with the minimum mass, gives a true mass of . Since the inclination is high, there is a small chance that the planet transits. HD 81040 b HD
