Astronomical evidence
Kepler-16 b orbits Kepler-16. The saved catalog gives an orbital period of 228.776 (+0.02/−0.037) days. Its discovery method is recorded as transit. These quantities describe the real astronomical setting behind the illustration. [1] The orbit of Kepler-16 b surrounds both members of its stellar binary. Transits across moving stars are more complicated than a planet repeatedly crossing one stationary stellar disk: the timing and duration depend on where each star is when the planet passes. The binary and planet must be modeled together. [1] The catalog radius is 8.4493 ± 0.0291 Earth radii. The mass entry is 105.833 ± 5.085 Earth masses. The source papers and full table retain the provenance of each parameter. [1]
The illustrated viewpoint
Humanoid / tentacled basalt sovereign. An invented moon of circumbinary planet Kepler-16 b, in an interpretive telephoto composition. The two host stars are real, while the moon, terrain and humanoid are fictional. The smaller cooler star is shown crossing part of the warmer star in an illustrative alignment. Stellar disks are enlarged for visual explanation; this is not a predicted eclipse or a calibrated naked-eye sky. The gas giant is outside the frame.
