KIC data

Kepler-30 is a star in the northern constellation of Lyra. It is located at the celestial coordinates: Right Ascension 19h 01m 08.0746s Declination +38° 56′ 50.218″. [2] With an apparent visual magnitude of 15.5, [3] this star is too faint to be seen with the naked eye. Kepler-30 is exhibiting a strong starspot activity. [6]

Planetary system

Three planets of Kepler-30 were detected by the transit method in 2011. [7] The planets are strongly interacting each other, with transit times variability exceeding one hour for each consecutive orbit. [8] Due to the irregularity of orbits, confirmation of the planetary system was delayed until 2012. [9] The planetary periods are close to 1:2:5 orbital resonance but are not resonant, producing an extremely complex orbital dynamics. [10]
