Ice Giant
Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (7.3x Earth) with significant water, carbon, and nitrogen content, characteristic of ice giants.Ice giants like Uranus and Neptune have icy interiors with thick atmospheres of hydrogen and helium, but not enough to be classified as gas giants.

No solid surface — any water is locked in a supercritical mantle and hot ice, not oceansgeology90
Active geology recycles nutrients and drives carbon cyclerotation10

Moon 1recedingOcean world - life0.63% - 11.7 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 73/100).
Moon 2rings0.010% - 1.5 radii
Inside the Roche limit (1.92 planet radii): torn apart into a ring system.
Moon 3rings0.010% - 2.0 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 4rings0.010% - 2.5 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 5merged0.010% - 4.1 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
