Astronomical evidence
Kepler-34 b orbits Kepler-34. The saved catalog gives an orbital period of 288.822 (+0.063/−0.081) days. Its discovery method is recorded as transit. These quantities describe the real astronomical setting behind the illustration. Kepler-34 b moves around two stars rather than a single central sun. In such a system, the distances and directions to both light sources change as the binary and the planet move. A convincing two-sun view requires their positions, sizes and luminosities at a specified epoch. A catalog entry alone does not supply that rendered sky. The catalog radius is 8.564 (+0.135/−0.157) Earth radii. The mass entry is 69.92 (+3.496/−3.178) Earth masses. The source papers and full table retain the provenance of each parameter.
The illustrated viewpoint
The orbital room is fictional. Its window offers an illustrative view of the binary setting; the displayed stellar phases and apparent sizes are not an ephemeris calculation.
