Characteristics Physical characteristics
The planet is classified as a sub-Neptune, with a mass of determined by the radial velocity method, and a radius of determined by the CHEOPS telescope, with an uncertainty of less than 1.7%. The object's average density is . Such a low value indicates a higher proportion of volatiles or a hydrogen-helium mixture in its composition.
Orbit The orbital period around its host star is approximately Earth days. The semi-major axis of the orbit is estimated to be . The equilibrium temperature is approximately 858 K, or 584 °C.
