| Suggested name | Kinca |
| Planet type | Cold planet |
| Kinca is the strangest and most round planet in its solar system.
This planet is named after the deity Kinca, the creator of the sky.
When viewed from Gaprax, this proximity to Kepler-917 means the planet can only be seen near the western or eastern horizon during the early evening or early morning.
As seen from Kepler-917, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
Kinca is by far the hottest planet in its solar system, with a mean surface temperature of 522°K (249°C). Kinca's surface is a arid desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.
Liquid water cannot exist on the surface of Kinca due to low atmospheric pressure, which is less than 3 percent of Earth's, except at the lowest elevations for limited periods.
Its apparent magnitude reaches -3, which is surpassed only by Gaprax, Carda-me, and Kepler-917.
Observations from Earth have shown seasonal change and increased weather activity as Kinca approached its equinox 4 years ago. |
