Resonances in the Early Evolution of the Earth-Moon System
Open accessAbstract
Most scenarios for the formation of the Moon place the Moon near Earth in low-eccentricity orbit in the equatorial plane of Earth. We examine the dynamical evolution of the Earth-Moon system from such initial configurations. We find that during the early evolution of the system, strong orbital resonances are encountered. Passage through these resonances can excite large lunar orbital eccentricity and modify the inclination of the Moon to the equator. Scenarios that resolve the mutual inclination problem are presented. A period of large lunar eccentricity would result in substantial tidal heating in the early Moon, providing a heat source for the lunar magma ocean. The resonance may also play a role in the formation of the Moon.

In the citing paper
“This resulting satellite has a mass of 0.69 M ☾ and a nearly circular orbit with a periapsis of 7.1 R ⊕ , far outside the Roche limit of ∼2.9 R ⊕ and even likely beyond the evection and eviction resonances for a moderate rotation period (Touma & Wisdom 1998;Ćuk & Stewart 2012).”

In the citing paper
“This conflicts with the initial orbital tilt away from the equator of 10° or higher that could explain the Moon's present-day ∼5° inclination (Touma & Wisdom 1998;Ćuk et al. 2016).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
