  So, this is a final resolution to the Planet X mystery? The one which Batygin predicts?

  • kjs3
    Planet X is supposed to be Neptune sized. This thing is less than 1000 miles across. 'Giant' for a Kupier belt object; not so much for planets.

    Doubt it, it's too small (even the upper end of the estimated size range has it smaller than Pluto). Batygin and Brown's predicted planet would have to be bigger than Earth.

  A giant "dwarf" planet? So...just a regular-sized planet, then?

  • alexwy
    With their current use of terminology a regular-sized planet would be a small medium at large.

      It's obviously Venti.

  Now we can make movies about rogue planets menacing Earth, not just asteroids. Great.
