Figure 1 (left): Artist's impression of the simultaneous stellar eclipse and planetary transit events on Kepler-1647. Such a double eclipse event is known as a syzygy. (Figure credit: Lynette Cook)

Figure 2 (right or below): Comparison of the relative sizes of several Kepler circumbinary planets, from the smallest, Kepler-47 b, to the largest, Kepler-1647 b. Kepler-1647 b is substantially larger than any of the previously known circumbinary planets. (Figure credit: Lynette Cook)

Figure 3: A bird's eye view comparison of the orbits of the Kepler circumbinary planets. Kepler-1647 b's orbit, shown in red, is much larger than the other planets (shown in gray). For comparison, the Earth's orbit is shown in blue. (Figure credit: B. Quarles)

Figure 4: A standalone version of the artistic impression of the planet Kepler-1647 b. Given that the planet is nearly identical to Jupiter in both size and mass, the planet is expected to be roughly similar in appearance. But it is much warmer - Kepler-1647 b is in the habitable zone.
