Fictional info (?)
Suggested nameMathe
Planet typeLarge hot gas giant
The planet is named after the deity Mathe, the god of war.

Mathe is gravitationally locked with HD 85628 A in a 2:1 spin-orbit resonance, and rotates in a way that is unique in its solar system.

Mathe's surface appears slightly bruised and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

The largest moon, Arabeb, has a diameter greater than that of the planet Mercury.
