Except comets do not originate from unstable planet satellites.
THIRD time of asking, why offer a citation as part of your OP claim, when that citation contradicts your claim?

Our moon has passed through the new phase at least 48 billion times since its formation. Not once in all that time has it undergone a significant alteration in its orbit, let alone spun off on its own.

That means the forces on it do not change over the course of its orbit, either monthly or epochally.

In fact, we have never detected any evidence of any moon spontaneously leaving its parent planet (without the intimate involvement of a third interfering massive body).

Your conjectures don't match what we observe.

In the new moon phase, when the orbital velocities of the planet and satellite are equal, the centrifugal force acting on the satellite from the Sun is zero.

It's always zero. There's no such thing as centrifugal force as a separate force. What you think of as centrifugal force is simply Newton's First Law in action; an object will not change its motion unless a force acts on it. A moon above a planet will be drawn towards the planet via its gravity. If it is moving fast enough relative to the planet, it will always "miss" - it will be pulled down, but by the time it starts moving downward significantly, it has moved to a different part of the planet. Thus the various gravitational forces sum to zero over the course of an orbit, and it does not move out of that orbit.

The only force that the moon (or the Earth) sees is gravity.

What's the point of making completely unevidenced, ridiculous claims like that, on a science forum?

Aaaaand - away we go into woo-land.

Let me try. The moon is made of cheese, and since everyone likes cheese, the moon is intentionally staying out of reach of people so they won't eat it. It's scared, you see, which is why it stays above 100 feet so no one can use a ladder to reach it. That's really the only logical explanation.

https://en.m.wikipedia.org/wiki/Comet

A comet is born when a satellite, orbiting a planet during the new moon phase, breaks out of orbit.
Having left the planet's orbit, the satellite moves against the rotation of the Sun, due to which the centrifugal force of the satellite is reduced, and as a result, the satellite rushes towards the Sun.
https://en.m.wikipedia.org/wiki/Halley's_Comet
If the orbital speed of the satellite is greater than the orbital speed of the planet, then the satellite moves around the Sun in a retrograde orbit.
https://en.m.wikipedia.org/wiki/Retrograde_and_prograde_motion
The eccentricity of a comet's orbit can be expressed using the following formula. E = Vp/Vs.
Jupiter's orbital speed is - 12 km/sec.
Io's orbital speed is - 17 km/sec.
https://www.researchgate.net/figure/Solar-System-Moons-Separations-and-Radii_tbl1_256459609
Rotating around the common center of mass of the pair, the planet and satellite are in a state of orbital resonance.
At aphelion, the orbital resonance of the system - the planet and the satellite - increases.
https://en.m.wikipedia.org/wiki/Orbital_resonance
Pluto moves around the Sun in a highly elongated orbit.
Perhaps Pluto orbited Neptune, then entered orbital resonance with Neptune and left orbit.
https://en.m.wikipedia.org/wiki/Pluto
Also, the stability of the orbits of satellites of small planets is reduced by orbital inclination and eccentricity.
Comets are also formed as a result of the retrograde motion of planetary satellites.

In the new moon phase, when the velocities of the planet and satellite are equal, the centrifugal force acting on the satellite from the Sun is zero.

Dude. It's just wrong. Never mind your hypothesis, the ideas you base it on are demonstrably not true.


Here's some examples:

We have zero evidence of any moon breaking away from its orbit spontaneously. It defies the laws of physics.

Here is Pluto's compared to the rest of the planets:

Pluto has an eccentrivity of .25, which is not much more than Mercury's .21.

Much more likely: It originated in the Oort cloud and had its orbit disturbed to one that passed through the inner solar system. Then, on one of its subsequent passes, a close encounter with one of the gas giants altered its orbit into one with a shorter period.

Hi all!
Mechanics of comet motion.

A comet is born when a satellite, orbiting a planet during the new moon phase, breaks out of orbit.
Having left the planet's orbit, the satellite moves against the rotation of the Sun, due to which the centrifugal force of the satellite is reduced, and as a result, the satellite rushes towards the Sun.
https://en.m.wikipedia.org/wiki/Comet
If the orbital speed of the satellite is greater than the orbital speed of the planet, then the satellite moves around the Sun in the opposite direction.
https://en.m.wikipedia.org/wiki/Retrograde_and_prograde_motion
In the new moon phase, when the orbital speed of the planet and the satellite are equal, the centrifugal force acting on the satellite from the Sun is zero.
Perhaps for this reason, the sun's gravity tore apart Comet Shoemaker-Levy as the comet orbited Jupiter synchronously and then capsized.
https://en.m.wikipedia.org/wiki/Centrifugal_force
The eccentricity of a comet's orbit can be expressed using the following formula. E = Vp/Vs.
Jupiter's orbital speed is 12 km/sec.
The orbital speed of Jupiter's satellite Metis is 31 km/sec.
https://www.researchgate.net/figure/Solar-System-Moons-Separations-and-Radii_tbl1_256459609
Metis, synchronously rotating around Jupiter and its own axis at a speed of one revolution per 7 hours, is slowly approaching Jupiter.
And everything that rotates, including satellites, has the properties of a gyroscope, maintaining the vertical position of the axis in space regardless of the rotation of the Earth.

When the axial and orbital speed of the satellite reaches a critical point, the satellite, having the properties of a gyroscope, overturns, due to which the synchronous rotation of the satellite is transformed into asynchronous.
During a satellite capsize, a centrifugal force appears, due to which the satellite breaks into fragments, like the Shoemaker-Levy comet.
Further, one part of the satellite fragments leaves orbit, and the other crashes into the planet.
https://en.m.wikipedia.org/wiki/Comet_Shoemaker–Levy_9
Perhaps the asteroid belt was formed from the torn apart satellites of Jupiter; the asteroid belt may be located next to Saturn.
https://en.m.wikipedia.org/wiki/Asteroid_belt
Asteroids, rotating around their axis and in orbit, periodically collide with meteorites, due to which the asteroid, having the properties of a gyroscope, first sways due to a violation of the center of mass, and then overturns, leaves orbit and moves towards the Sun.
The above can be easily verified by experiment.
The stability of the orbits of planetary satellites is reduced by orbital resonance and eccentricity.
Perhaps the gyroscope has other unstudied properties, one of them is the Dzhanibekov effect. https://en.m.wikipedia.org/wiki/Orbital_resonance
Anticyclones also have gyroscope properties, due to which anticyclones are blocked.

You're using words you don't understand here.

No. Shoemaker-Levy disintegrated due to tidal, not centrifugal, "force." Force is in quotes because neither is a true force; it is the result of other forces acting on the body (like momentum and gravity.)
Further, one part of the satellite fragments leaves orbit, and the other crashes into the planet.

No. Even during a tidal disintegration, all the fragments generally either hit the planet or continue in their orbit, depending on the original orbit.
Perhaps the asteroid belt was formed from the torn apart satellites of Jupiter; the asteroid belt may be located next to Saturn.

But the asteroid belt is NOT located next to Saturn, so your theory doesn't hold. In addition, the most likely 'origin story' for the asteroid belt is that they are simply fragments left over from the original formation of the solar system; the presence of Jupiter perturbed their orbits enough that they could never coalesce into planets as fragments in the other parts of the Solar System did.

Meteorites are bodies that came from planetary space and impacted the Earth. You are thinking of meteoroids, which are small bodies still in space.
due to which the asteroid, having the properties of a gyroscope, first sways due to a violation of the center of mass, and then overturns, leaves orbit and moves towards the Sun.

Again, no. If that does happen (an asteroid's spin increases enough) it will tend to separate into pieces, each one following a nearly identical orbit to the original bodies. No "falling into the Sun."

A mishmash of errors, incorrect terms, partially understood physics and unrelated Youtube videos.

The Sun's gravity will not be able to tear Mercury apart, because the tidal force is too small and depends on the diameter of the planet, and not on the distance from the Sun to the planet. https://en.m.wikipedia.org/wiki/Tidal_force
The Sun's gravity will only be able to tear Mercury apart if Mercury begins to wobble and then topple over.
