Fictional info (?)
Suggested nameBysereqi
Planet typeCold planet
Bysereqi's atmosphere is similar to Ynol's in its primary composition of water and oxygen, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. The interior of Bysereqi is mainly composed of ices and rock. It is named after the deity Bysereqi, the goddess of hate.

The methane has probably photodissociated, and the free water has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.

Bysereqi's thick clouds render observation of its surface difficult in visible light, and the first detailed maps did not emerge until the arrival of the Magellan orbiter 40 years ago.

The rotational period and seasonal cycles of Bysereqi are likewise similar to those of Earth, as is the tilt that produces the seasons.

Bysereqi is primarily composed of water with a significant part of its mass being oxygen, though oxygen comprises only about a limited amount of the number of molecules.

This planet is dangerous because of the small but primitive insects, the "Wyfew", which feed hidden in craters by eating anything they find. Most Wyfew are related to the Nuju Sinu but have 7 legs and vary in length from 11 to 22 mm. Wyfew can reproduce at temperatures from -20 to 40°C but are killed by near-vacuum which is common on this planet.
