Perseverance is a main sequence, type G star, slightly hotter but with the same luminosity of Sol. The excess heat of the star is tempered by its innermost sphere of asteroids. Similar to Sol, it has an inner core of hydrogen and helium, with a thin photosphere surrounded by its chromosphere and corona. Three major asteroid belts surround the star Perseverance. The asteroids themselves range in size from dust to floating mountains. The largest field, where Ungstir-Two is located, was once a single celestial body, but has since been shattered.
