Pluto looks great in tie-dye, doesn’t it? I will, I swear, wear tie-dye for a week straight if the make it a planet again.
Pluto is, or isn’t, a planet. You’ll pick the answer that will be right on a 2nd grade science test, that no, it’s a dwarf planet. So would I. I want that A like a cat wants to catch that laser.
But I think not! Pluto has an atmosphere, unlike Mercury- even though it’s as thin as my patience with a homework load exceeding the weight of 15 pounds. It retains its own shape, which is nearly spherical. It isn’t a moon. Okay. So, the IAU definition requires that a planet have vacuumed up or thrown away the surrounding neighborhood of debris, asteroids, and other random space bric-a-brac. The thing is, though, If Neptune had cleared its orbit, there wouldn’t a Pluto to argue about. And Jupiter has thousands of asteroid (Trojans- it’s really, really complicated, that’s a post for later) hanging around along its orbit. Even Earth has a Trojan, as we’ve discovered recently. SO, technically, a couple of the planets shouldn’t be planets. We’re just keeping them until you give Pluto back, IAU!
But’s that’s just the scientific reason to change the IAU definition. Now to the classic I-just-want-Pluto-back bit. Alright. So you’ve seen the Pluto photo with the big heart, right? Well, I’m just gonna go with Stephen Colbert on this one. I personally don’t like texting language, but it’s <3ing us! Pluto’s like, “I wanna be a planet when I grow up”. Best KBO (Kuiper belt object) in the Solar System! Let’s hope the IAU agrees eventually.
Do you think Pluto should still have Planet status??
It’s an amazing world of science out there…let’s go exploring!
