| Suggested name | Hyoo |
| Planet type | Warm planet |
| Its orbital period around HD 108147 of 11 earth days is the shortest of all the planets in its solar system.
It is named after the deity Hyoo, the god of chaos.
As seen relative to the fixed stars, it rotates on its axis exactly four times for every four revolutions it makes around HD 108147.
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 120°K (-153°C) at night to 420°K (147°C) during the day across the equatorial regions.
As the closest planet to Kebo, Hyoo has been a prime target for early extra solar exploration.
Liquid water cannot exist on the surface of Hyoo due to low atmospheric pressure, which is less than 7 percent of Earth's, except at the highest elevations for short periods. |
