Why is this a Gas Giant?Your planet has 65.0% hydrogen and helium, combined with a mass of 15.0x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 2merged0.063% - 6.9 radii
Merged with an adjacent moon: too close for both to hold a stable orbit.
Moon 3crashed0.056% - 5.9 radii
Inside the synchronous orbit: tidal decay dragged it down - it struck the planet ages ago.
Moon 4rings0.056% - 9.7 radii
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Moon 5receding0.050% - 15.4 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Moon 6receding0.050% - 26.1 radii
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
