Kepler-47b, as well as Kepler-47c, was first discovered by scientists, from both NASA and the Tel-Aviv University in Israel, using the Kepler space telescope.[1][2] Additionally, the planetary characteristics of both objects were identified by a team of astronomers at the University of Texas at Austin's McDonald observatory.[1][3] Both planets were discovered after transiting their parent stars, and they both seem to be orbiting along the same plane.[2]
