| Suggested name | Eifeid |
| Planet type | Cold planet |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
Eifeid has been known to astronomers since antiquity. It is named after the deity Eifeid, the creator of prosperity.
As seen relative to the fixed stars, it rotates on its axis exactly four times for every three revolutions it makes around HD 118904.
Eifeid's surface appears quite cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.
Eifeid is by far the hottest planet in its solar system, with a mean surface temperature of 413°K (140°C).
The two polar ice caps appear to be made largely of frozen gas. |
