| Suggested name | Hacho |
| Planet type | Cold planet |
| This planet is named after the deity Hacho, the demon of dreams.
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 90°K (-183°C) at night to 1015°K (742°C) during the day across the equatorial regions.
It may have had sulfur dioxide oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.
The rotational period and seasonal cycles of Hacho are likewise similar to those of Chama, as is the tilt that produces the seasons.
Optical ground-based telescopes are typically limited to resolving features about 330 kilometers across when Hacho is closest because of Chama's atmosphere. |
