Scientific American posts article about evidence of a new planet

And get this , it's 10X earth size and in our oot cloud, they show how they were reviewing the orbits of the objects we can see and when they modled the orbits the best fit was a large mass...

I've read more details about this. There is no direct evidence of the planet, just some statistical evidence that there might be a planet. And other reviews of the information show it may not as real as thought.

Astronomers discover largest solar system -> A large gas giant with a million year orbit around the parent star.

Moreover, the same claims that "the orbital math requires another planet of at least uranian mass around orbiting near 2x the orbital radius of Neptune" have been made since the 1920's... which lead Lowell to have Tombaugh look for the mystery purported giant, and instead he found Pluto. (And lots of asteroids).

It's the same story as 100 years ago. A few mathematical hints, and no hard evidence.

Don't believe in planet [o]X[/o] IX until they actually image the sucker.

Reactionless drives have more real evidence than the "5th gas giant" does.

And since the Voyager Probes, the orbital perturbation has been determined to be a result of an incorrect estimation of the exact masses of Uranus/Neptune. With the revised mass-data from the Voyager 2 probe, the orbit of Neptune was determined to be an exact fit for the data, IIRC.

But of course that only means there is no large planet (i.e. Jovian/Neptunian sized) orbiting somewhere around or in the midst of the inner Kuiper Belt.

But the Ixians of House Vernius make some of the Padishah Emperors' finest technology . . .

I remember as a kid wondering why no one ever followed up on the Pluto thing. I don't recall where I read it but even in the early 70s astronomy articles aimed at the general public took it as established fact that Pluto was too small for the orbital permutations of Uranus and Neptune to be explained.

You'd think there would be some more work on that. Or that I could have been an astronomer, worked it on myself, and have had 5 minutes of fame. And maybe naming rights.

Persephone would be a good name, IMHO.

Well, I missed that little tidbit of info.

And you can't trust an Ixian...
