Astronomical evidence
Kepler-47 c orbits Kepler-47. The saved catalog gives an orbital period of 303.227 (+0.062/−0.027) days. Its discovery method is recorded as transit. These quantities describe the real astronomical setting behind the illustration. Kepler-47 c is part of a system with several planets orbiting a stellar pair. The system demonstrates that a circumbinary environment can host more than one planetary orbit. Comparing the planetary periods describes the architecture, while detailed gravitational modeling is needed to evaluate orbital evolution. The catalog radius is 4.65 (+0.09/−0.07) Earth radii. The mass entry is 3.17 (+2.18/−1.25) Earth masses. The source papers and full table retain the provenance of each parameter.
The illustrated viewpoint
The atmospheric habitat is fictional. Gas clouds, lighting and any protective structure shown here are extrapolations rather than resolved observations.
