Astronomical evidence
Kepler-452 b orbits Kepler-452. The saved catalog gives an orbital period of 384.843 (+0.007/−0.012) days. Its discovery method is recorded as transit. These quantities describe the real astronomical setting behind the illustration. Kepler-452 b has a period slightly longer than an Earth year in the saved catalog. Its mass is calculated from a mass–radius relationship, and the local snapshot carries a controversial-status flag. Both qualifications matter when discussing how securely its physical properties are known. The catalog radius is 1.63 (+0.23/−0.2) Earth radii. The listed mass of 3.29 Earth masses is inferred from a mass–radius relationship. The source papers and full table retain the provenance of each parameter.
The illustrated viewpoint
The sheltered landscape is fictional. Similar orbital periods do not imply identical stellar irradiation, atmospheres or climates, and no detailed surface is established by the transit data.
