The interior structure of the Moon is constrained by its mass, moment of inertia, and k2 and h2 tidal Love numbers. We infer the likely radius, density, and (elastic limit) rigidity of all interior layers by solving the inverse problem using these observational constraints assuming spherical symmetry. Our results do not favor the presence of a low rigidity transition layer between a liquid outer core and mantle. If a transition layer exists, its rigidity is constrained to 43−9+26 GPa, with a… 

Viscous Dissipation in the Fluid Core of the Moon

The spin axes of the mantle, fluid core, and solid inner core of the Moon precess at frequency Ωp = 2π/18.6 years−1 though with different orientations, leading to viscous friction at the core‐mantle

The Cassini State of the Moon's Inner Core

We present a model of the precession dynamics of the Moon that comprises a fluid outer core and a solid inner core. We show that three Cassini states associated with the inner core exist. The tilt

Viscoelastic Relaxation within the Moon and the Phase Lead of Its Cassini State

Analyses of Lunar Laser Ranging data show that the spin symmetry axis of the Moon is ahead of its expected Cassini state by an angle of ϕp = 0.27 arcsec. This indicates the presence of one or more

Observational Constraint on the Radius and Oblateness of the Lunar Core‐Mantle Boundary

Lunar laser ranging (LLR) data and Apollo seismic data analyses, revealed independent evidence for the presence of a fluid lunar core. However, the size of the lunar fluid core remained uncertain by

A Past Lunar Dynamo Thermally Driven by the Precession of Its Inner Core

The Cassini state equilibrium associated with the precession of the Moon predicts that the mantle, fluid core, and solid inner core precess at different angles. We present estimates of the

The Origin of the Moon Within a Terrestrial Synestia

The giant impact hypothesis remains the leading theory for lunar origin. However, current models struggle to explain the Moon's composition and isotopic similarity with Earth. Here we present a new

Effect of Thermal State on the Mantle Composition and Core Sizes of the Moon

Abstract —Based on the joint inversion of seismic and gravity data in combination with phase equilibrium calculations within the Na2O–TiO2–CaO–FeO–MgO–Al2O3–SiO2 system using the method of Gibbs free

Geodetic Evidence That Mercury Has A Solid Inner Core

Radio tracking measurements of the MESSENGER spacecraft while in orbit about Mercury has yielded new estimates for the planet's gravity field, tidal Love number, and pole coordinates, confirming the equilibrium state with an estimated mean (whole-planet) obliquity ϵ of 1.968 ± 0.027 arcmin.

Determination of Global Density Inhomogeneities and Stresses Inside the Moon

The possible distribution of density and stress anomalies in the interior of the Moon is determined. For this purpose, we have developed a new solution of the incorrect inverse gravimetry problem



Lunar interior properties from the GRAIL mission

The Gravity Recovery and Interior Laboratory (GRAIL) mission has sampled lunar gravity with unprecedented accuracy and resolution. The lunar GM, the product of the gravitational constant G and the

GRAIL gravity constraints on the vertical and lateral density structure of the lunar crust

We analyzed data from the Gravity Recovery and Interior Laboratory (GRAIL) mission using a localized admittance approach to map out spatial variations in the vertical density structure of the lunar

Toward a mineral physics reference model for the Moon’s core

The results indicate that the seismic velocities proposed for the Moon’s inner core by a recent reanalysis of Apollo seismic data are well below those of γ-Fe, which provides strong constraints to seismic models of the lunar core and cores of small telluric planets.


In the recent paper (1) lunar interior models by complementing Apollo seismic travel time data with selenodetic data which have recently been improved by GRAIL and LLR. Important information on the

Gravity Field of the Moon from the Gravity Recovery and Interior Laboratory (GRAIL) Mission

The Moon's gravity field reveals that impacts have homogenized the density of the crust and fractured it extensively, and GRAIL elucidates the role of impact bombardment in homogenizing the distribution of shallow density anomalies on terrestrial planetary bodies.

Internal structure of the Moon inferred from Apollo seismic data and selenodetic data from GRAIL and LLR

The internal structure of the Moon is important for discussions on its origin and evolution. However, the deep structure of the Moon is still debated due to the absence of comprehensive seismic data.

Constraints on mantle anelasticity from geodetic observations, and implications for the J2 anomaly

SUMMARY We use geodetic observations of the Earth to constrain anelasticity in the Earth’s mantle at periods between 12 hr and 18.6 yr. The observations include satellite laser ranging (SLR)
