When astronomers announced Kepler-452b, they were not just adding another distant world to a growing catalog. They were pointing to a planet that orbits a star much like our own, in a region where ...

Orbital properties of the 70 cool giants. A comparison of the derived orbital eccentricities from this work (y-axis) versus the orbital periods (previously known) for our planetary candidates sample.

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 ...
