Magnetic FieldModerate Activity
Why is this a Ice Giant?Your planet has moderate mass (5.9x 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.

Moon 1stable0.00010% - 100.0 radii
Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
Moon 2receding0.16% - 11.3 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
