Info for exoplanet "Petho"

Fictional info (?)
Suggested name		Petho
Planet type		Cold planet
In English, Petho is often referred to as the "gray planet" because the helium prevalent on its surface gives it a pale gray appearance that is unusual among the astronomical bodies visible to the naked eye. It is named after the deity Petho, the bringer of dreams. As seen from Kepler-587, in a frame of reference that rotates with the orbital motion, it appears to rotate only once every two years. Petho's surface appears heavily cratered and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years. Petho's hazy clouds make observation of its surface challenging in infrared light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 52 years ago. The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. In late February 1300, Petho was visited by the New Horizons probe, which used Petho's gravity to increase its speed and bend its trajectory en route to Thyreidi Mona.
