| Ergwu Dyang |
| Cold planet |
| As seen from DE CVn, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years.
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 65°K (-208°C) at night to 595°K (322°C) during the day across the equatorial regions. |
