Suggested name | Wakaechu |
Planet type | Large hot gas giant |
This large hot gas giant is named after the deity Wakaechu, the messenger of destruction.
As seen relative to the fixed stars, it rotates on its axis exactly two times for every two revolutions it makes around WASP-43.
Wakaechu's axis has the smallest tilt of any of its solar system's planets. Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 170°K (-103°C) at night to 910°K (637°C) during the day across the equatorial regions.
The smooth Borealis basin in the northern hemisphere covers 25 percent of the planet and may be a giant impact feature.
Wakaechu is primarily composed of AlO, with a significant part of its mass being K,, though K, comprises only about a small fraction of the number of molecules. It may also have a rocky core of heavier elements, but like the other large hot gas giants, Wakaechu lacks a well-defined atmosphere.
Observations from Earth have shown seasonal change and increased weather activity as Wakaechu approached its equinox 3 years ago. |
