That's terrifying, no? A whole planet (yes a dwarf one, but still a PLANET) is just rogue and will wander through the orbit of Sol as it pleases.

[Pxtl]

It's not a rogue planet, that implies Interstellar. This is an object with a very long orbit that takes it out to he Oort cloud but still - a permanent resident of the solar system.

It's basically just an exceptionally large comet. It's not Melancholia.

Love that movie

[Pxtl]

It needs a sequel.

It made me so nauseous I had to stagger out of the cinema.

> I would estimate at an albedo of 0.01-0.08 a diameter of 130-370 kilometers (nominally 160) which puts it on a similar scale, if not larger than, Sarabat's huge comet C/1729 P1, and almost undoubtedly the largest Oort Cloud object ever discovered- almost in dwarf planet territory!

So a bit less dramatic but still really cool.

For reference, a nominal 160km diameter would put it around the same size as the 40th largest asteroid known. Huge for an object coming from the oort cloud, but not really huge in comparison to other rocky bodies in the solar system.
