Far-out worlds, just waiting to be foundIN THE dark reaches of the solar system lurk swarms of hidden worlds. Too small and too distant to reflect sunlight, they have remained under the cover of darkness for billions of years. But now the outer solar system is giving up its secrets. And with them comes an astonishing claim: "It's quite possible that there is a halo of planets surrounding our solar system, just waiting to be found," says Eugene Chiang, an astronomer at the University of California, Berkeley.

What makes Chiang's claim so surprising is the sheer number and size of these planets. Weighing more than Mars, they dwarf Sedna and Quaoar, the largest rocky bodies spotted circling the sun beyond Pluto.
