| Suggested name | Mathe |
| Planet type | Cold planet |
| The planet is named after the deity Mathe, the spirit of love and beauty.
Like Iali Te, Mathe has been orbiting HD 219077 within Listeph's orbit as an inferior planet, and never moves more than 25 degrees away from HD 219077. When viewed from Iali Te, this proximity to HD 219077 means the planet can only be seen near the western or eastern horizon during the early evening or early morning. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to HD 219077, which reoccurs over the so-called synodic period approximately every 191 days.
Mathe is gravitationally locked with HD 219077 in a 3:2 spin-orbit resonance, and rotates in a way that is unique in its solar system.
Mathe's axis has the smallest tilt of any of its solar system's planets.
Mathe is shrouded by an opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.
Mathe is primarily composed of ozone with a significant part of its mass being carbonyl sulfide, though carbonyl sulfide comprises only about a limited amount of the number of molecules.
Observations from Earth have shown seasonal change and increased weather activity as Mathe approached its equinox 6 years ago. |
| Atmosphere | Ozone | 81% |
| Carbonyl sulfide | 10% |
| Sulfur dioxide | 4.6% |
| Xenon | 3.2% |
| Atmospheric pressure | 21 bar |
