The real world, in the literature
The host system is real. All alien organisms, robots, societies and social histories are fictional. Moons, rings, terrain and weather are artistic assumptions unless specifically supported by a cited source. These images are not calibrated simulations of the sky.

NASA composite catalog values may combine different papers. Errors and upper/lower limits are retained. “Calculated Value” means derived or estimated. Msini is a minimum mass. Missing values are unknown. A multiple-star system’s single stellar row does not describe every component. Equilibrium temperature is not a measured surface temperature.
