| Erenar-axon |
| Cold planet |
| It has the longest rotation period (445 days) of any planet in its solar system and rotates in the opposite direction to most other planets.
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 50°K (-223°C) at night to 945°K (672°C) during the day across the equatorial regions.
It is radically different from Earth in other respects.
Wind speeds can reach 50 metres per second. |
