Is Pluto actually a planet? | The Tylt
Pluto was downgraded to dwarf planet over 10 years ago, but it's something that still seems so damn unfair. How do you take away its planet status after 76 years? On the other hand, science is governed by rules. Without them, we have nothing. But put aside the reclassification determined by an arbitrary meeting of space nerds, we want to know what you think. Is Pluto a planet? Vote now! 🌌
Is Pluto actually a planet?
Humor aside, there is legitimate contention on how to classify Pluto.
Alan Stearn, planetary scientist, believes Pluto is a planet.
It's a planet. Science doesn't work by voting. Did people vote on the theory of relativity? No! It's either right or it's wrong. Do we vote on whether genetics is a good theory or not? Of course not. Either data supports the observations or they don't. Voting doesn't work in science.
Pluto is as far across as Manhattan to Miami, but its atmosphere is bigger than the Earth's. It has 5 moons, it has atmosphere, weather. If it walks like a duck, it's a duck. We're showing the world this beautiful planet. And it's a double planet, which is even more awesome.
But because of an arbitrary ruling from a space union (not as glamorous as it sounds), these people think they're right in saying that Pluto is not a planet.
Pluto met the first two of the these criteria, but the last one proved pivotal. "Clearing the neighbourhood" means that the planet has either "vacuumed up" or ejected other large objects in its vicinity of space. In other words, it has achieved gravitational dominance.
Because Pluto shares its orbital neighbourhood with other icy Kuiper Belt Objects, the resolution effectively stripped the distant world of a planetary designation it had held for some 76 years.
It was immediately relegated it to the distinct category of "dwarf planet", alongside the biggest body in the asteroid belt, Ceres, and other large Kuiper Belt Objects such as Eris, Quaoar and Sedna.
NASA stands by their classification of Pluto.
These people think Pluto is a dwarf planet.
Same. Here are a bunch of people who believe that Pluto is a planet.
