| Suggested name | Prax |
| Planet type | Cold planet |
| It is the second-brightest natural object in the night sky after Dikemona, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, often, visible to the naked eye in broad daylight.
For this reason, scientists often classify Prax and Dikemona as "cold planets" to distinguish them from the other planets. This cold planet is named after the deity Prax, the god of destruction.
In November 2700, NASA reported finding a large amount of underground ice in the Utopia Planitia region of Prax.
Prax can easily be seen from Dikemona with the naked eye, as can its brownish coloring. Optical ground-based telescopes are typically limited to resolving features about 330 kilometers across when Prax is closest because of Earth's atmosphere. |
