[00:00:00]For nearly two decades, [music] Pluto has been officially classified as a dwarf planet. But a growing rebellion of planetary [music] scientists is fighting to reverse that decision, arguing that our current [music] definition of a world is fundamentally flawed.

[00:00:15]In 2006, the International Astronomical [music] Union declared that a planet must clear its orbital neighborhood.

[00:00:22]Because Pluto shares [music] the Kuiper Belt with thousands of icy bodies, it was demoted. However, [music] leading researchers now push for the geophysical planet definition.

[00:00:32]>> [music] >> This new standard states that a planet is any celestial body with enough gravity to pull itself into a sphere, >> [music] >> regardless of its orbit.

[00:00:42]If this definition is adopted, it would not only reinstate Pluto, but it would add over 150 new planets to our solar [music] system map. This includes moons like Earth's moon and distant worlds scattered up to 7.5 billion kilometers, or 4.6 [music] billion miles away. Pluto itself is a complex world, sitting [music] roughly 5.9 billion kilometers, or 3.7 billion miles from the sun. Despite surface temperatures [music] plunging to -232° C, or -387° [music] F, Pluto possesses towering mountains of solid water ice and vast plains of frozen nitrogen.

[00:01:27]Scientists argue [music] that geology should define a planet, not just its location in space.

[00:01:33]A spherical body with active [music] geology, an atmosphere, and a complex core is a world in its own right.

[00:01:41]As we [music] send probes further into the dark, our understanding of the universe must evolve.

[00:01:47]The fight for Pluto [music] is not just about simple nostalgia. It is about recognizing the true diversity of our [music] cosmic neighborhood.
