How the heck do we mistake Pluto for a planet for a century and miss a "real ninth planet?
-
@scottalanmiller I think it has to do with how far out it is.... its estimate closest point to the sun is 5x further out then pluto.

Yeah, they said it is 20x the distance of Neptune, and Neptune is even farther out than Pluto (on average.)
-
@scottalanmiller The data suggests an eliptical orbit of ranging from 200AU at the periapsis and and up to 1200AU at apoapsis. Neptune averages 30AU from the sun.
-
that's about 20x then
-
Of course it may not exist at all... the models they ran are explaining what may be affecting orbits of smaller objects from the kuiper belt.
-
It will be interesting to see if they actually find it.

Watch it be a Black-hole to some little girl's bookshelf..

It's also possible on a different plane than the rest of our planets. that's what the models I saw yesterday suggested.
-
Pluto is, makes sense that it would be.
-
@Dashrender It would pretty much have to be... a planet the size they are suggesting can't form that far out (assuming theories are correct on how planets form), which means it formed closer and gravity from another star passing by most likely flung it out that far and changed its plane.

Interesting, didn't read that as an explanation. Though I suppose it makes sense.

I read that on another news story about it somewhere else...

This is what is in store for us in the next 24 hours or so. More snow at once than we've seen in years. Almost reminds me of when I was a kid. Now I'm just a bigger kid with bigger toys to play in the snow with. Lol Anywhere from 6-14 inches is what we keep hearing.

I read a little about this because my 7yo is all about space. She loved it. A mystery planet.

@coliver On the fullscale image you can barely see the orbits of the planets in the glow of the sun.

Right, it is incomprehensible how much bigger this orbit is then the orbits of our known planets are. Although this is still a hypothesis from what I've seen... cool none-the-less.

Cool is an understatement!!!!
