| Suggested name | Pina |
| Planet type | Terrestrial |
| Pina is the largest and most crater filled planet in its solar system. It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
The planet is named after the deity Pina, the bringer of nature.
Like Bebber-tho, Pina has been orbiting K2-187 within Noethi's orbit as an inferior planet, and never exceeds 29 degrees away from K2-187.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Pina's distance from K2-187 is only about two-thirds (or 40 pct) of its distance at aphelion. Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 90°K (-183°C) at night to 840°K (567°C) during the day across the equatorial regions. |
