New Horizons has FINALLY settled a most basic question of the deposed 9th planet of the solar system - "How big is Pluto?"
The data returned from 3 billion miles away says Pluto checks in at 1,473 miles (2,370 kilometers) in diameter.
This makes Pluto the largest of the four other dwarf planets known to exist beyond the orbit of Pluto.
Be sure to tune in tomorrow morning for the flyby.
