A stable K-type star with moderate flare activity and a temperature of 4,800 K. It provides the perfect warmth for life within its habitable zone.
A small, barren rocky planet with a thin CO₂-rich atmosphere. Tidally locked to the star, it features rugged, metallic craters with iridium deposits.
A rocky, volcanic planet with a thin, toxic atmosphere of SO₂ and CO₂. It has a faint ring and sulfur geysers spread across its volcanic plains.
The habitable, temperate-dry world of the system. It has high-salinity oceans, geothermal activity, and a hardy biosphere adapted to intense sunlight and mineral-rich terrain.
A large gas giant with swirling storm patterns and iridescent ammonia clouds. It has prominent rings and four moons of varied composition.
A dense, carbonaceous asteroid belt containing carbon, organic compounds, and water ice, with some asteroids potentially hosting ancient microbial fossils.
