• The star is always high in the sky on the bright face, it hangs on horizon in the twilight zone, while the cold dark face is in permanent darkness.
• The world experiences libration - a regular wobble - as it orbits, causing the star to move in the sky.

It orbits within the prime region of its star's habitable zone.

• It receives moderate levels of stellar energy.
