I've been doing some thinking on a sci-fi story about a colony around a Red Dwarf Star. I understand that most planets around Red Dwarf Stars, at least in the habitable zone, would be tidally locked. I created another thread to ask about ways to maintain a planetary rotation. My main question...

All, A couple of questions about planets around Red Dwarf Stars: I'm imagining a planet around a Red Dwarf Star...think Trappist-1...and want to know how I can prevent tidal locking for an Earth-sized terrestrial planet in such a star's habitable zone...say, 1/50th to 1/20th of an AU from the...

Thanks.

Quick question from an amateur: Assume you have a tidally locked rocky planet around a red dwarf star. I've heard that a magnetic field is or can be dependent upon the rotation of a planet (I've read that the lack of rotation of Venus was a possible reason for the weak magnetic field among...

I have a sci-fi idea regarding being able to move planets around like billiard balls. I'm theorizing that, after a nova, some of the bands of material around a star formed a new ring of rocky planets around a Neutron Star. Naturally, these are bathed in radiation. Having never taken high...

Thanks all.

Question from an amateur: The Earth's plates seem pretty large compared to the planet. This example has about 20 to 30 with about 6 seemingly making up the majority of the Earth's surface. Is there a reason why they are so large? I'm writing a novel in which a planet, instead of having 20 to...

I would have it as a very short "month" of perhaps 30 to 60 hours due to close co-orbit of the two mutually locked bodies.

Thank. Any idea how large the bulge/permanent tide would be? As for the lesser tides of a slowly rotating / very close to tidally locked world, how much weaker would b they be with this lesser rotation? Interestingly, this scenario may have a much longer "day" than "month". Assume two...

You would not have a planetary rotation but would have an mutual orbital rotation with the other body. Is that enough for a dynamo to keep going or does the planet itself have to rotate on its axis to keep that liquid metal flowing? From the surface of the moon, you would see the stars and sun...

Non-Scientist here. Assume that you had a two body system (planet-moon, double-planet) where one of the bodies was very close to tidally locked. Say they are closely co-orbiting at 6 to ten diameters in a relatively quick 20 to 50 hour orbit. One of the planets is close to being tidally...

All, Non-scientist amateur looking for an answer. I understand that planetary rotation aid is vital to maintain a magnetic dynamo. Venus' slow reverse rotation is often used as an explanation for its odd low magnetic field. Assume there is a moon or a double planet that is tidally locked...

Does anyone know how long the lunar month was when the moon was formed? I can't get the equation to work. I'm looking for speed of the moon when it was created at about 1/10th the current distance from the earth. Thanks.

Here is the Caster System:

I believe that Circumbinary orbits are quite common, are they not, at least for planets around stars? I've seen many artist representations but I don't know of the specifics of the system. From the planet's point of view, it has already been kicked out (or formed out there) and orbit the two...
