R. I. P. oppy!! we love you so much
“What’s perhaps most remarkable is that we can make a simple, mathematical relationship between a world’s mass and its orbital distance that can be scaled and applied to any star. If you’re above these lines, you’re a planet; if you’re below it, you’re not. Note that even the most massive dwarf planets would have to be closer to the Sun than Mercury is to reach planetary status. Note by how fantastically much each of our eight planets meets these criteria… and by how much all others miss it. And note that if you replaced the Earth with the Moon, it would barely make it as a planet.”
It was a harsh lesson in astronomy for all of us in 2006, when the International Astronomical Union released their official definition of a planet. While the innermost eight planets made the cut, Pluto did not. But given the discovery of large numbers of worlds in the Kuiper belt and beyond our Solar System, it became clear that we needed something even more than what the IAU gave us. We needed a way to look at any orbiting worlds around any star and determine whether they met a set of objective criteria for reaching planetary status. Recently, Alan Stern spoke up and introduced a geophysical definition of a planet, which would admit more than 100 members in our Solar System alone. But how does this stand up to what astronomers need to know?
As it turns out, not very well. But the IAU definition needs improving, too, and modern science is more than up to the challenge. See who does and doesn’t make the cut into true planetary status, and whether Planet Nine – if real – will make it, too!

So beautiful. With everyone on lockdown, pizzas are finally returning to their natural habitat. The earth is healing, we are the virus. 🙏
What the Italian Prime Minister said: We will reopen cautiously and with responsibility.
What Italians understood: ALL FREEEEEE!!!!!!
@wallflower-koharu You DIDN'T need to apologize. Your first comment was written when this CoVid was supposed to be fake news, and it's okay to make questions about being more widespread in Italy than in other countries! It was a legittimate ask! The others who ignored you instead to reply should apologize, they were rude as hell. It was normal/It still is to question why. C'MON! And @valerieandsylveon actually you didn't need to apologize either. Okay, there are stupid racist in Italy too, but nowhere the level America is facing. And Olive Garden sucks lol. And that's true. Never touch an Italian's food lmao.
