25. 08. 2021

There is a massive exoplanet in orbit around star Kepler-1704. Long-term radial velocity measuring now show mass of the exoplanet and parameters of its orbit around star. Orbit of this exoplanet is highly eccentric with periastron (closest to the star) 0.16 AU a apoastron 3.9 AU (furthest from the star).
