| Suggested name | Berche |
| Planet type | Cold planet |
| It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 63°K (-210°C), and has a complex, layered cloud structure with xenon thought to make up the lowest clouds, and molecular hydrogen the uppermost layer of clouds. This cold planet is named after the deity Berche, the goddess of prosperity.
Its orbital eccentricity is the largest of all known planets in its solar system; at perihelion, Berche's distance from HD 142415 is only about two-thirds (or 50 pct) of its distance at aphelion. Berche'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.
The ozone has probably photodissociated, and the free molecular hydrogen has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
A prominent result is the "great yellow spot", a giant storm that is known to have existed for centuries since it was first detected by scanner. |
