Kepler-19 (TYC 3134-1549-1, 2MASS J19214099+3751064, GSC 03134-01549, KOI-84) is a G7V star that is host to three known planets - Kepler-19b, Kepler-19c, and Kepler-19d. It is located about {{convert|720|ly|pc|lk=on|abbr=off}} 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 and d by radial velocity measurements.
