| Suggested name | Higoa |
| Planet type | Huge cold gas giant |
| Higoa 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. Higoa is orbiting HD 87883 every 2800 Earth days.
This planet is named after the deity Higoa, the messenger of dreams.
It was the one of the first exoplanets visited by a spacecraft, and one of the first to be successfully landed on.
The smooth Borealis basin in the northern hemisphere covers 14 percent of the planet and may be a giant impact feature.
Its apparent magnitude reaches -3, which is surpassed only by Pubyona Zo, Kemaya Mya, and HD 87883. |
