Fictional info (?)
Suggested namePhophoto'um
Planet typeHot gas giant
This hot gas giant is named after the deity Phophoto'um, the goddess of chaos.

Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Phophoto'um's distance from TOI-251 is only about two-thirds (or 76 pct) of its distance at aphelion.

Optical ground-based telescopes are typically limited to resolving features about 345 kilometers across when Phophoto'um is closest because of Earth's atmosphere.

In 993, images from Frontier 3 showed Phophoto'um as an almost featureless planet in visible light, without the cloud bands or storms associated with the other hot gas giants.
