| Suggested name | Enot |
| Planet type | Huge cold gas giant |
| The interior of Enot is mainly composed of ices and stone. The planet is named after the deity Enot, the spirit of war.
As seen relative to the fixed stars, it rotates on its axis exactly four times for every three revolutions it makes around HD 81040.
The ammonia has probably photodissociated, and the free helium has been swept into interplanetary space by the solar wind because of the lack of a 2H2O layer.
Optical ground-based telescopes are typically limited to resolving features about 510 kilometers across when Enot is closest because of Earth's atmosphere.
Its north and south poles, therefore, lie where most other planets have their equators. |
