Is an extreme precession on a tidally locked planet possible?
Let's assume an exoplanet orbits a red dwarf star closely enough that is tidally locked to it. Is it possible for the planet to have a significant axial precession? If not naturally, is it possible to ...

How close to a host star can a tidally locked planet be and its dark side still maintain a moderate temperature?
So, imagine an atmosphere-less planet, tidally locked to a sun-like star. How close to the star can the planet be before its dark side becomes too hot?
I imagine that at some point the rocks on its ...

If all the Trappist-1 planets are tidally locked, which ones may have temperate zones?
Since all the Trappist-1 planets have circular orbits, it is entirely likely that all them are tidally locked.
If so, which ones of the planets may have temperate zones either on the bright or dark ...

Where did the idea that tidally-locked planets have a big hurricane come from?
I've been noticing a bit of a trend in the depiction of tidally-locked habitable planets, where they are shown having a huge hurricane-like storm over the daylight hemisphere. Here's an example, and ...

Can tidally locked planets have liquid oceans on their night side, and would such a planet be habitable?
Let's say we have a tidally locked planet orbiting a star. And let's say that the conditions on its surface are just right for water to exist on its surface. Conventional wisdom says that the water on ...

Why do planets in red dwarf star systems tend to have a higher probability to get tidally locked?
I have read about about the habitability of red dwarf systems on Wikipedia, as well as some web articles on similar topics. The problem is, it does not explain why and how it happened. Google search ...

Could iron rain upset tidally locked WASP76b?
The Jupiter mass planet WASP76b orbits its 1.5*Sunmass star at 0.03AU and is tidally locked. The day side heats to 2400C which vaporizes metals, including iron observed in its atmosphere. The balmy ...

A "tidally locked" double planet?
First, I'd like to take the definition of a "double-planet" as two bodies orbiting each other where the center of gravity is not inside the larger body. Also, the system would have to fill other ...

Are exoplanets at dwarf stars less likely to have super-rotating atmospheres or asynchronous tidal locking?
Dwarf stars have terrestrial sized planets orbiting in habitable zones very close to them. These exoplanets are often said to be tidally locked to their star, like the Moon is to Earth, and that they ...

(How) Can one determine if an exoplanet is synchronously tidally locked or not? [duplicate]
Mercury is asynchronously tidally locked so that all of its surface regularly sees the Sun. But an exoplanet which is synchronously locked to its star, could we tell that it is? It would have a hot ...
