Astronomical evidence
TOI-1338 b orbits TOI-1338 A. The saved catalog gives an orbital period of 95.4001 (+0.0062/−0.0056) days. Its discovery method is recorded as transit. These quantities describe the real astronomical setting behind the illustration. TOI-1338 b is a circumbinary planet even though the catalog’s host field names TOI-1338 A. That naming convention should not be read as a claim that its orbit surrounds only one component. Joint interpretation of stellar and planetary events is essential to the system’s physical model. The catalog radius is 7.661 ± 0.053 Earth radii. The mass entry is 11.3 ± 2.1 Earth masses. The source papers and full table retain the provenance of each parameter.
The illustrated viewpoint
The free-fall orbital habitat is invented. The illustration does not establish artificial gravity, a particular station orbit or a calibrated appearance of both stars.
