The rotation period of the celestial bodies Kepler-1647b around the double star is 1107 day.
Astrophysics from the USA and South Korea discovered in the vicinity of the double star exoplanet, which is the largest of the known satellites in this type of systems. Scientists do not exclude the habitability of the found object. The study is published in The Astrophysical Journal.
The rotation period of the celestial bodies Kepler-1647b around the double star is 1107 day. In size it is similar to Jupiter, and is located in the habitable zone of their system (that is, where the possible existence of liquid water).
The system Kepler-1647 located at a distance of 3.7 thousand light-years from Earth in the constellation Cygnus. Its age is estimated at 4.4 billion years old (slightly younger than the Earth). The system consists of two stars which by their physical characteristics resemble the Sun.
Exoplanet Kepler-1647b open transit method (tracking the change in the brightness of the lights when passing it to the disk of a celestial body) by the space telescope Kepler. First Kepler-1647b observed in 2011, however, the analysis and verification of the data took several years. Scientists plan to continue research.
