Suggested name | Stephthrymr Obe |
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.
The planet is named after the deity Stephthrymr Obe, the demon of prosperity.
Stephthrymr Obe's axis has the smallest tilt of any of its solar system's planets.
Two spacecraft have visited Stephthrymr Obe: Wayfinder 6 flew by 18 years ago; and Messenger, launched 25 years ago, orbited Stephthrymr Obe over 60 times in four years before exhausting its reactor and crashing into the planet's atmosphere 10 years later.
The atmospheric pressure at the planet's surface is 0.013 bar, or roughly the pressure found 675 m under the oceans of Earth.
Its apparent magnitude reaches -3, which is surpassed only by Raxcal, Palkaka'thoca, and HD 224693.
Like a few of the other cold planets, Stephthrymr Obe has a ring system, a magnetosphere, and numerous moons, Briel being the most studied one. |
