Fictional info (?)
Suggested nameOneleao Mede
Planet typeCold planet
Oneleao Mede is the smallest and most round planet in its solar system. Oneleao Mede is the fourth planet from HD 50554 and the second-smallest planet in its solar system.

The interior of Oneleao Mede is mainly composed of ices and molten metal. This planet is named after the deity Oneleao Mede, the bringer of war.

Like Phaëbauti, Oneleao Mede has been orbiting HD 50554 for 4.6 billion years, and never moves more than 14 degrees away from HD 50554.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Oneleao Mede's distance from HD 50554 is only about two-thirds (or 56 pct) of its distance at aphelion. The polar regions are constantly below 198°K (-75°C).
