Kepler-30

Kepler -30 is a sun-like star that is orbited by three exoplanets.

Exoplanets

It was demonstrated that the three planets of the system ( Kepler - 30b, Kepler - 30c and Kepler - 30d ) orbits in the equatorial plane of the star, as in our solar system.

Kepler - 30b has an orbital period of 29.3 days and is about 11 Earth masses and 4 Earth radii of the smallest known companion (like Neptune). Kepler - 30c orbits in about 60 days around its sun. He is the most massive and largest known exoplanet system with about 2 Jupiter masses and a radius of about 12 Earth radii. Kepler - 30d has an orbital period of 143 days, a mass of about 23 Earth masses and a radius of 9 Earth radii.
