| Suggested name | Mathemedeia |
| Planet type | Cold planet |
| In English, Mathemedeia is often referred to as the "blue planet" because the carbon dioxide prevalent on its surface gives it a pale blue appearance that is distinctive among the astronomical bodies visible to the naked eye. It is the second-brightest natural object in the night sky after Euan Puck, reaching an apparent magnitude of -5 - bright enough to cast shadows at night and, often, visible to the naked eye in broad daylight.
This cold planet is named after the deity Mathemedeia, the spirit of good fortune.
Mathemedeia's axis has the smallest tilt of any of its solar system's planets.
Mathemedeia is primarily composed of hydrogen deuteride (HD) with a significant part of its mass being carbon dioxide, though carbon dioxide comprises only about a tiny fraction of the number of molecules.
Mathemedeia has been explored on several occasions by robotic spacecraft, most notably during the early Pioneer and Wayfinder flyby missions and later by the Hawking orbiter.
In 1092, images from Frontier 7 showed Mathemedeia as an almost featureless planet in visible light, without the cloud bands or storms associated with the other cold planets. |
