This latest addition to the still-small family of CBPs defies the current trend of known short-period planets orbiting near the stability limit of binary stars. Unlike the previous discoveries, the planet revolving around the eclipsing binary system Kepler-1647  has a very long orbital period (∼1100 days) and was at conjunction only twice during the <jats:italic>Kepler</jats:italic>  mission lifetime. Due to the singular configuration of the system, Kepler-1647b  is not only the longest-period transiting CBP at the time of writing, but also one of the longest-period transiting planets. With a radius of 1.06 ± 0.01 <jats:italic>R</jats:italic>\n                  <jats:sub>Jup</jats:sub>, it is also the largest CBP to date. The planet produced three transits in the light curve of Kepler-1647  (one of them during an eclipse, creating a syzygy) and measurably perturbed the times of the stellar eclipses, allowing us to measure its mass, 1.52 ± 0.65 <jats:italic>M</jats:italic>\n                  <jats:sub>Jup</jats:sub>. The planet revolves around an 11-day period eclipsing binary consisting of two solar-mass stars on a slightly inclined, mildly eccentric (<jats:italic>e</jats:italic>\n                  <jats:sub>bin</jats:sub> = 0.16), spin-synchronized orbit. Despite having an orbital period three times longer than Earth’s, Kepler-1647b  is in the conservative habitable zone of the binary star throughout its orbit.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382544418484870030","@type":"Researcher","foaf:name":[{"@value":"Veselin B.
