It is located about 720 light-years (220 parsecs) away in the constellation Lyra, five arcminutes northwest of the much more distant open cluster NGC 6791. Planetary system There are three known planets in the Kepler-19 planetary system. Planet b was discovered by the transit method, c by transit-timing variations[7] and d by radial velocity measurements.[8] The Kepler-19 planetary system[8][4] Companion(in order from star) Mass Semimajor axis(AU) Orbital period(days) Eccentricity Inclination(°) Radius b 8.4+1.6−1.5 M🜨 0.0846±0.0012 9.2869900 0.12±0.02 89.94+0.06−0.44 2.209±0.048 R🜨 c 13.1±2.7 M🜨 — 28.731+0.012−0.005 0.21+0.05−0.07 — — d 22.5+1.2−5.6 M🜨 — 62.95+0.04−0.30 0.05+0.16−0.01 — — References ↑ Roman, Nancy G.
