文摘
- •
The early lunar orbital evolution is coupled with lunar magma ocean evolution.
- •
Evection resonance is unstable due to overheating of the Moon.
- •
The limit cycle reduces Earth-Moon's angular momentum without overheating the Moon.
- •
A large tidal Q of the early Earth facilitates the system's angular momentum loss.
