HD 81040 b is a massive gas giant exoplanet that orbits the star HD 81040, discovered in 2005 by radial velocity. Its orbital period is just over 1000 days. It has a semimajor axis of about 1.95 AU, and its orbit is quite eccentric, at a little over 0.5. Astrometry of HD 81040 using Gaia, published in several papers, has determined an orbital inclination of about 111°. This, combined with the minimum mass, gives a true mass of 7.53 MJ. Since the inclination is high, there is a small chance that
