Gaia

Analysis of the radial velocity data allowed for a better understanding of the orbits of the two planets. By comparing historical data from the Hipparcos and Gaia space missions, the movement of the star was used to constrain the tilt, or inclination, of the orbit of the outer planet, HD 65216 c. The study determined that HD 65216 c has an eccentric orbit with a period of approximately 7007 days. Assuming the two planets lie in the same orbital plane, their true masses are calculated at 2.23 ...
