  1. 💁🏻‍♀️ TIL: 🪐❄️ #Pluto’s reclassification as a #dwarfplanet in 2006 continues to prompt debate.

    Scientists disagree about the #IAU’s definition of a #planet, particularly its requirement that a planet clear its orbital neighborhood. The discussion also considers #Eris, #NewHorizons #findings, and competing approaches to classifying worlds in the #solarsystem.

    #Spacecraft also measures the distribution of gas in the outer #heliosphere, the expansive, protective bubble formed by a steady stream of particles that release from the sun called the #solarwind.

  14. An ancient moonpocalypse may explain #Neptune’s odd #moon #Nereid
    The strange satellite was born in a steady, circular orbit around Neptune, then tossed into its elongated orbit during a chaotic encounter with a #Pluto-sized body that ejected or pulverized all its sibling #moons. This idea counters assumption that Nereid formed in #KuiperBelt, the cold reservoir of #space rocks in outer #solarsystem, and was pitched into its present orbit later.

  19. I hope we live long enough to witness and discover what JWST knows about the Altjira system in its "eclipsing season" which is scheduled to survey the next 10 years (9 now), where the outer body will be frequently positioned between the inner body and the sun to confirm whether it's a triple system. It's currently classified as a binary system.

  22. "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.

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. cosmiclog.com/2026/05/08/pluto #astronomy #planetary #science

  30. 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 that's not typically found around objects so small.
