It has a volume of around one and three quarter Earths (i.e. a radius roughly one a quarter times Earth's) but not significantly more mass or gravity, since the iron core of the planet is only about 20% of its radius. It is spinning gradually and generating a magnetic field, but this is weaker than Earth's.

Nekenalos' atmosphere is a touch thicker (as in, spanning more altitude) than Earth's and laced with more carbon dioxide. Coupled with its slightly increased proximity to the primary star, Nekenalos has a hotter climate on average than Earth does, and possesses no permanently icy poles. The altitude temperature gradient is comparable to that of Earth, making even equatorial mountains quite chilly. The weather tends to favour thunderstorms, and one of the biggest threats to certain areas are bushfires started by lightning strikes. Since Nekenalos has no notable wobble to its orbit, seasons are non-existent.
