Of course, a discussion among politicians won't get #Pluto reclassified back as a planet. Scientists & astronomers decide criteria for a planet. Pluto is either in or out of that definition.

I wonder what criteria that would define Pluto as a planet would not also apply to our Moon, a.k.a. Luna. Are we ready for Earth🌎/Luna🌗 to be officially a binary planet system? After trying to be the center of our universe for all of history, could we take that step? #astronomy #planetary #science

"Pluto-like world’s thin atmosphere poses a mystery" by @cosmiclog / @alanboyle - A thin atmosphere may have been observed around a #KuiperBelt object a quarter Pluto's size. As the minor planet crossed in front of a star, telescopes saw light go out and come back slowly rather than instantly. And since Alan is author of "The Case for Pluto" book, he mentions a recent public discussion among politicians about reclassifying Pluto as a planet. https://cosmiclog.com/2026/05/08/pluto-like-worlds-thin-atmosphere-poses-a-mystery/ #astronomy #planetary #science

Pluto-like world’s thin atmosphere poses a mystery

Scientists are puzzling over another oddball on the edge of the solar system: This time, it’s an icy object less than a quarter of Pluto’s size with a thin atmosphere – a layer of gas t…

Congratulations to Heike Rauer! 🎉

I had the pleasure of experiencing her work firsthand in a colloquium at my former institute while I was still a student, and I remember her as an outstanding #planetary scientist. A very well-deserved recognition!
