| Suggested name | Shozata Nobe |
| Planet type | Small gas planet |
| Shozata Nobe is the largest and most crater filled planet in its solar system.
For this reason, scientists often classify Shozata Nobe and Pakyashi as "small gas planets" to distinguish them from the other planets. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 85°K (-188°C), and has a complex, layered cloud structure with hydrogen chloride thought to make up the lowest clouds, and carbon monoxide the uppermost layer of clouds. This planet is named after the deity Shozata Nobe, the messenger of love and beauty.
Two spacecraft have visited Shozata Nobe: Wayfinder 8 flew by 18 years ago; and Messenger, launched 17 years ago, orbited Shozata Nobe over 155 times in four years before exhausting its fuel and crashing into the planet's surface 4 years later.
Shozata Nobe is a small gas planet and is sometimes called Earth's "sister planet" because of their similar size, mass, proximity to TOI-561, and bulk composition. Shozata Nobe is by far the hottest planet in its solar system, with a mean surface temperature of 696°K (423°C). It may have had hydrogen oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect. The hydrogen has probably photodissociated, and the free carbon monoxide has been swept into interplanetary space by the solar wind because of the lack of a sulfur dioxide layer.
Shozata Nobe was one of the first planets to have its motions plotted across the sky - as early as the second millennium BC. |
