Astronomical evidence
Kepler-16 b is a cold giant planet orbiting both stars of an eclipsing binary. Stellar eclipses and planetary transits established its circumbinary geometry. [2] The saved catalog reports a period of 228.776 days, with +0.020/−0.037 uncertainty. [1] The two suns and giant planet provide the astronomical anchor. The foreground is an invented moon because the giant does not provide a terrestrial surface; the cited observations do not establish such a moon or a lush environment.
The illustrated viewpoint
Rajiv sits cross-legged in meditation in an open, vine-covered stone pavilion. Rain falls over a green mountain valley and waterfalls. A weathered creature relief covers a pillar; a blue gas giant and two low suns appear through the clouds. The moon, temperate rainy climate, breathable air, green organisms, waterfalls, stone pavilion, artwork and human presence are fictional. Kepler-16 b receives relatively weak stellar irradiation; this lush climate is not a climate prediction or a consequence of its measured orbit. The giant’s blue clouds, apparent size, phase, sky position and the stellar separation are artistic. No moon stability or sky-geometry calculation is claimed.
