Fictional info (?)
Suggested nameNapima Mi
Planet typeCold planet
In English, Napima Mi is often referred to as the "brown planet" because the helium prevalent on its surface gives it a pale brown appearance that is distinctive among the astronomical bodies visible to the naked eye. It is the second-brightest natural object in the night sky after Osuge Su, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.

The planet is named after the deity Napima Mi, the bringer of fear.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Napima Mi's distance from HD 114386 is only about two-thirds (or 76 pct) of its distance at aphelion.

Liquid water cannot exist on the surface of Napima Mi due to low atmospheric pressure, which is less than 5 percent of Osuge Su's, except at the lowest elevations for short periods.

The latest probe to visit the planet is Juno, which entered into orbit around Napima Mi after a slightly lengthy voyage.
