Answer #1

There is a peculiar clustering of six previously known objects that orbit beyond Neptune.
Remaining hiccups in Uranus's orbit led scientists to think that there might yet be one more planet.
Sedna's odd, far-flung orbit made it the most distant known object in the solar system at the time. Its perihelion, or closest point to the sun, lay at 76 AU, beyond the Kuiper belt and far outside the influence of Neptune's gravity.
Kuiper belt objects have been discovered, and their origins are largely unexplained. "Not only are they there[the objects], but they are in exactly the places we predicted."
