It is located at the celestial coordinates:Right Ascension 19h 01m 08.0747s Declination +38\u00b0\u00a056\u2032\u00a050.219\u2033.[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[edit]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 irregularity of orbits, confirmation of 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]References[edit]^ “Lyra \u2013 constellation boundary”, The Constellations, International Astronomical Union, retrieved 2011-12-15^ a b c d e f Brown, A.
