Heze

Heze, known officially as ζ Virginis (Zeta Virginis), is a binary star system located in the Virgo constellation 74 light-years (23 parsecs) from Sol. The system holds the Heze (Zeta Virginis A) star as its barycentric stellar body, orbited by six planets and an outer companion star, Zeta Virginis B, or Rouge.

The Heze system is most known for the presence of Avalon, a highly unusual habitable planet in its grasp. However, that isn’t to say the other planets don’t have their own rich histories and oddities.

Heze
The Heze star is a main-sequence A-type star with twice the mass and radius of Sol, possessing an effective temperature of 8,131°C. It is only half a billion years old, making it remarkably young in the system and home to very young planets with the exception of Avalon, which is almost 3 billion years older than the star itself.

Compared to Sol, Heze has violent solar winds, much higher radiation levels, and a further habitable zone. While Heze IV is within the habitable zone, Heze III alternates between too close and too far, causing its extreme seasons.



Heze I
A brown and yellow world with high amounts of sulphur and phosphorus tinting its surface a sickly brownish yellow. Its proximity means it receives immense solar winds and radiation from Heze, baking the planet and eroding its surface.

The planet is geologically active, with volcanoes scattered throughout the surface and occasional magma eruptions.
