The astronomer whose work helped kick Pluto out of the pantheon of planets says he has good reason to believe there's an undiscovered planet bigger than Earth in the far reaches of our solar system.

RENEE MONTAGNE, HOST:

Good morning. I'm Renee Montagne. Caltech astronomer Mike Brown helped prove Pluto is not a true planet. Brown tweets under the handle plutokiller. But his young daughter does not approve. She wanted Pluto to stay a planet, and she said she wouldn't forgive him until he discovered a brand new one. Now he thinks he has. Brown and another astronomer say small bodies appear to be orbiting a giant icy planet far beyond Pluto called Planet Nine. Thanks, Dad. It's MORNING EDITION.
