Pluto is originally classified as the ninth planet of our Solar System, but it was reclassified as a dwarf planet in 2006 by the International Astronomical Union. On examination of the orbital characteristics of Pluto, my belief is that the planet is not a member of our Solar System, but rather, it orbits with a center of rotation, a possible dark matter center just outside of our Solar System.
Specifically, the orbit of Pluto is highly elliptical and is not in the same plane as that of the other eight planets of our Solar System. Given that solar system formation necessitates the nucleation of dust and particles into astronomical objects in circular orbit around the star, and importantly, in the same plane, Pluto could not have been part of our Solar System since it formed about 4.5 billion years ago.
Additionally, close examination of the orbit of Pluto would reveal that the dwarf planet does not orbit the Sun as its center of rotation; rather, Pluto’s center of rotation in its orbit is a possible dark matter body, transparent to optical and infrared observations. Hence, with a solar system comprising planets whose center of rotation in their orbits being the star, Pluto cannot be classified as a planet of our Solar System since its orbital center is not the Sun.
Therefore, Pluto cannot be part of our Solar System given that its plane of orbit is not the same as that of the other eight planets of our Solar System. In addition, Pluto’s center of orbital rotation is not the Sun, but rather, a possible dark matter body, which is transparent (and not detectable) to infrared and optical telescopes, both on Earth and in space. Personally, I would classify Pluto as an exoplanet; thereby, making it the nearest exoplanet to Earth.
