How will the Solar tides affect the Earth's rotation once it is tidally locked to the Moon?

user177107 should be commended for asking this clever question. In short, the described configuration is possible, at least in principle. It will bring two elements into the dynamics. First, a large ...

Best way to quantify the tidal stress on an exoplanet?

A solution to this problem, along with some applications, is provided in the paper ``The Ability of Significant Tidal Stress to Initiate Plate Tectonics'' by Zanazzi & Triaud. More applications ...

Do moons of rocky oblate planets migrate to low inclination over time? If so, does the time it takes depend on the Moon's size?

To answer this question, we have to recall the definition of the Laplace surface. Conventionally called Laplace plane, this surface is not actually a plane. In the vicinity of a planet, it coincides ...

Can we measure planetary Love number of exoplanets?

In short, the answer is: yes. This paper provides an example of direct measurement of the tidal deformation of the close-in Jupiter WASP-103b whose quadrupole Love number turned out to be close to ...

Physical Meaning of the Principal Tidal Fourier Modes and Their Integers

In that paper, we actually applied the term "principal" to the semidiurnal mode $\omega_{2200}$. When the planet is not synchronised (i.e., when it is not showing the same side to the ...

Does a rotating moon experience greater tidal heating than a tidally locked equivalent?

The answer is: yes. In a synchronised moon, the tidal bulge is aimed, approximately, at the planet. Approximately -- because for a finite eccentricity the position of the planet as seen from the moon ...

Is the process responsible for Triton's nearly perfect circular orbit going to happen in my fictional world?

Tidal circularisation is produced by a combination of tidal dissipation in the planet and that in the satellite. Calculations performed for the Jovian and Saturnian moons inducate that for them the ...

Relative orientation in a 1:1 resonance of a planet and a satellite

The mean motion $n$ and the time-derivative of the true anomaly ${\nu}$, are related by $$ n\,=\,\frac{(1-e^2)^{3/2}}{(1+\cos f)^{2}}~\dot{\nu}~~. $$ Therefrom it is clear that in the pericentre (i.e.,...

When did the Moon become tidally locked to Earth?

Gerald provided a link to an article on how the bodies that hit the near side of the Moon were accelerated by the Earth. Originally posted on December 1, 2010, revised June 2, 2013. The author, ...
