| Suggested name | Phaë |
| Planet type | Cold planet |
| It is named after the deity Phaë, the creator of good fortune.
An observer on Phaë would therefore see only one day every four years.
The volume of water ice in the south polar ice cap, if melted, would be sufficient to cover the entire planetary surface to a depth of 14 meters.
Phaë can easily be seen from Daphsto-nixna with the naked eye, as can its brownish coloring.
Phaë is primarily composed of nitrogen with a significant part of its mass being carbonyl sulfide, though carbonyl sulfide comprises only about a limited fraction of the number of molecules. Because of its rapid rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).
In late February 2300, Phaë was visited by the New Horizons probe, which used Phaë's gravity to increase its speed and bend its trajectory en route to Daphsto-nixna. |
