HSG 582 d is the ocean world of the system; making it vastly different from the other brown-like planets, it is a full blue marble when seen from space. Despite the conditions, planet d has no signs of any life forms, even deep in the oceans and near the twilight zone.
Your planet has abundant oxygen (26.0%) and hydrogen (12.3%), 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.
✓ 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.
