The outer bounds of our solar system seem to be constantly shifting further. With the advent of telescopes and other astrological tools, our understanding of the galaxy has reached new levels. Pluto, discovered in 1930 and once labeled definitively as the ninth planet in the Milky Way galaxy, is now under scrutiny. However, in the early 21st century, astronomers observed several orbiting bodies similar to Pluto. Two scientists debate the validity of labeling Pluto as a planet. Their arguments are presented below.

Scientist 1

Pluto is a planet. It follows an elliptical orbit around the sun, as does Earth, Jupiter, Saturn and so on. It has several moons that, because of gravitational forces, orbit the planet asymmetrically. Many astronomical bodies exist in the infiniteness that is outer space, and it is not surprising that several small bodies resembling Pluto be found in its outer reaches.

Pluto is not a planet in the formal sense. Rather, it is a dwarf planet. There are more massive bodies in the solar system that orbit the Sun. As such, Pluto is more debris-like than planet like, scattered to the outer bounds of the Milky Way after some cataclysmic explosion or collision.
