HD 81040 b

HD 81040 b is a massive gas giant exoplanet that orbits the star HD 81040, discovered in 2005 by radial velocity.

[2] 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.

[3][4] Astrometry of HD 81040 using Gaia, published in several papers, has determined an orbital inclination of about 111°.

[3][1][5][6][4] Since the inclination is high, there is a small chance that the planet transits.
