| Suggested name | Hyomyo |
| Planet type | Cold planet |
| Hyomyo is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Hyomyo is orbiting HD 216520 every 35 Earth days.
The planet is named after the deity Hyomyo, the messenger of destruction.
Hyomyo is a cold planet and is sometimes called Earth's "twin planet" because of their similar size, mass, proximity to HD 216520, and bulk composition. The atmospheric pressure at the planet's surface is 17 bar, or roughly the pressure found 945 m under the oceans of Earth. |
