| Suggested name | Pyanfu |
| Planet type | Warm gas giant |
| In English, Pyanfu is often referred to as the "yellow planet" because the ethane prevalent on its surface gives it a pale yellow appearance that is unusual among the astronomical bodies visible to the naked eye.
It is a warm gas giant planet with a mass one-thousandth that of HAT-P-15, but two-and-a-half times that of all the other planets in its solar system combined. This warm gas giant is named after the deity Pyanfu, the god of nature.
Pyanfu is gravitationally locked with HAT-P-15 in a 4:3 spin-orbit resonance, and rotates in a way that is unique in its solar system.
The atmospheric pressure at the planet's surface is 15 bar, or roughly the pressure found 450 m under the oceans of Earth.
As the closest planet to Mubaryo, Pyanfu has been a prime target for early interplanetary exploration. |
