Mechanics of comet motion.
https://en.m.wikipedia.org/wiki/Comet A comet is a satellite of a planet that fell out of the planet’s orbit during the new moon phase. 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%27s_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 calculated using the following formula.
E = Vp/Vs.
Jupiter's orbital speed is - 12 km/sec.
Io's orbital speed is 17 km/sec.
https://en.m.wikipedia.org/wiki/Dwarf_planet Perhaps Pluto is a comet that left the orbit of Neptune during the new moon phase.
https://en.m.wikipedia.org/wiki/Pluto 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.
The further a planet and its satellite are from the Sun, the greater the difference in their orbital speeds.
