Ja-no is a large terrestrial planet located within the outer region of the habitable zone, receiving less stellar warmth than Reynox while still remaining close enough to its star for potentially temperate conditions. Its surface holds cooler climates, broad rocky regions, and areas where ice, thin atmospheres, or cold-adapted environments are common. The planet has an average equatorial diameter of approximately 15989 kilometers and an average polar diameter of approximately 15792 kilometers. It orbits at approximately 2.61 AU from its star.
