Another factor in I.A.U 's ruling for Pluto?

Question

This is not a question ..

Thought this might be interesting to post for the Pluto debaters ..

another important factor to consider is before it was discovered by clyde Tombaugh and labeled a
planet .. it used to be a moon of neptune, broke away from it's gravity & then got caught in the sun's
gravity & orbited around that . It used to be that a planet was clasified as orbiting any star . Now it's the make up and size of a planet .

Answer 1

It's interesting you mentioned Pluto used to be a moon of Neptune .

Its called a Trans-Neptunian object (TNO) is any object in the solar system with all or most of its orbit beyond that of Neptune.

and here is another cool twist on your reasoning why pluto left neptune .. Some researchers have theorized that Pluto and its moon Charon were moons of Neptune that were knocked out of Neptunian orbit when Triton was captured !

Answer 2

Pluto being an escaped moon of Neptune is only one idea of where Pluto came from, but no one really knows if that's what really happened. Having talked with many professional astronomers, most feel that Pluto was probably never a moon of Neptune, but the possibility hasn't been disproven yet. As someone else said, it's more likely that Neptune's moon Tritan (which is similar in some respects to Pluto) may be a captured Kuiper Belt Object, and Pluto never got captured in the first place.

Answer 3

Pluto is a Kuiper's belt object (KBO). The IAU maintained it as a planet while Pluto was the largest KBO. However, today there are some KBOs
of similar or probably greater size than Pluto. It is highly improbable that Pluto was a satellite of Neptune. In fact, Triton is a KBO captured by
Neptune, just the opposite case.

Answer 4

I agree. Most people don't know that Pluto used to be a moon of Neptune, and they're really confused about the I.A.U's decision.
