If anyone is interested, here is its orbit, my old day job was to compute orbits for asteroids and comets.

(This uses wasm, meant for a desktop, and will download the asteroid catalog of about 65mb, you have been warned)

There was a lot of negative press and commentary about "demoting" Pluto from being a planet at the time. But its obviously true that it was the right move, and creating this "dwarf planet" class of objects was correct. It was hard to justify Pluto being a planet when Ceres exists, but Eris, Haumea, Makemake and all of these other possible Dwarf planets are the nail in the coffin.

Could this be Planet X? https://science.nasa.gov/solar-system/planet-x/

Pretty rad.

Is this Planet X that they have been talking about for a while now?

> The new dwarf planet candidate, called 2026 ED138, orbits on a plane tiled nearly 25 degrees

I've noticed similar glaring typos in 2 recent articles. In both cases very early in the article. Is it possible that they are adding typos intentionally to mask the AI authoring?
