Suggested nameMihya Mi
Planet typeWarm planet
Mihya Mi is the smallest and most crater filled planet in its solar system. It is the second-brightest natural object in the night sky after Chupyu, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, sometimes, visible to the naked eye in broad daylight.

Mihya Mi is similar in composition to Chupyu, and both have different bulk chemical composition from that of the larger warm planets. This planet is named after the deity Mihya Mi, the spirit of destruction.

When viewed from Chupyu, this proximity to K2-168 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Mihya Mi's distance from K2-168 is only about two-thirds (or 43 pct) of its distance at aphelion.

In 2880, images from Wayfinder 8 showed Mihya Mi as an almost featureless planet in visible light, without the cloud bands or storms associated with the other warm planets. Observations from Earth have shown seasonal change and increased weather activity as Mihya Mi approached its equinox 7 years ago.
