Trintos the the fourth planet of the system, and one of the two planets with simple multicellular life. It is claimed the star's growing brightness will affect Trintos in a billion years.
Your planet has abundant oxygen (16.2%) and hydrogen (36.8%), creating extensive water coverage while in the habitable temperature zone.
Water worlds have deep global oceans covering most or all of their surface. They form when planets have high water content and orbit in the habitable zone.
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Habitability
✓ Conditions could support lifeThis planet’s modelled conditions could support biological processes: stable temperatures, liquid water and the chemistry life as we know it needs. That makes life possible, not present.
