Suggested name | Thee Hy |
Planet type | Small cold gas planet |
Orbiting within Pamedeia's orbit, Thee Hy is an inferior planet and never appears to venture far from HD 219134; its maximum angular distance from HD 219134 (elongation) is 31 degrees.
This small cold gas planet is named after the deity Thee Hy, the bringer of fear.
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 110°K (-163°C) at night to 1120°K (847°C) during the day across the equatorial regions.
Optical ground-based telescopes are typically limited to resolving features about 405 kilometers across when Thee Hy is closest because of Earth's atmosphere. |
