| Suggested name | Sietar |
| Planet type | Hot planet |
| When viewed from Doraepi-ioao, Sietar can reach an apparent magnitude of -3, bright enough for its reflected light to cast shadows, and making it on average the third-brightest object in the night sky. Sietar's atmosphere is similar to Doraepi-ioao's in its primary composition of neon and helium, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. This hot planet is named after the deity Sietar, the messenger of nature.
Sietar's surface is a barren desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Sietar is primarily composed of neon with a significant part of its mass being helium, though helium comprises only about a limited amount of the number of molecules. A prominent result is the "great red spot", a giant storm that is known to have existed for centuries since it was first observed by radar. |
