Marius presents as swirling ochre and cream, with a great anticyclonic storm larger than some planets, with 9 moons spanning a wide range of orbital distances. A broad ring system of silicate dust and fragmented rock encircles the equatorial plane, its inner edge swept clear by tidal forces. Atmospheric temperatures range from −160 to 40°C in the upper atmosphere at 0.04 atm, with wind shear layers moving in opposite directions at different altitudes. At 68,992 km in diameter, its bulk is composed of hydrogen and helium outer layers over a metallic hydrogen interior. At a rarity score of 67, Marius is an uncommon find — not unique, but the specific configuration here is unlikely to repeat nearby.
