Astronomical evidence
Kepler-1647 b orbits Kepler-1647. The saved catalog gives an orbital period of 1107.5923 ± 0.0227 days. Its discovery method is recorded as transit. These quantities describe the real astronomical setting behind the illustration. Kepler-1647 b takes roughly three Earth years to complete an orbit around its two host stars. A long orbital period means fewer transit opportunities within a survey’s observing baseline. In a binary system, those crossings also depend on the positions of both stars, complicating the connection between a transit sequence and an orbit. The catalog radius is 11.8739 ± 0.1377 Earth radii. The mass entry is 483 ± 206 Earth masses. The source papers and full table retain the provenance of each parameter.
The illustrated viewpoint
The atmospheric moon is a fictional vantage. A moon’s existence, orbital stability and local weather would require evidence and modeling beyond the discovery of its parent planet.
