| Suggested name | Ioteus |
| Planet type | Large hot gas giant |
| The planet is named after the deity Ioteus, the god of war.
Ioteus is a large hot gas giant and is sometimes called Earth's "twin planet" because of their similar size, mass, proximity to Kepler-1658, and bulk composition. It has the densest atmosphere of the two large hot gas giants, consisting partly of formaldehyde. Ioteus is by far the hottest planet in its solar system, with a mean surface temperature of 522°K (249°C), even though Liarosa is closer to Kepler-1658. It may have had 2H2O oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
Its apparent magnitude reaches -3, which is surpassed only by Liarosa, Liafran Li, and Kepler-1658.
A prominent result is the "great black spot", a giant storm that is known to have existed for centuries since it was first observed by radar.
The Ioteus system has a unique configuration among those of the planets because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. |
