Kepler-19 (TYC 3134-1549-1, 2MASS J19214099+3751064, GSC 03134-01549, KOI-84)[4] is a G7V star that is host to three known planets - Kepler-19b, Kepler-19c, and Kepler-19d. 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.
