Dimly lit by a far distant sun, a planet much larger than Earth may orbit in the vast outer reaches of the solar system, eluding our telescopes for more than 400 years. But its presence may leave telltale traces. And as new and more powerful probes join our space exploration armada, even the immensity of space may no longer afford Planet X a hiding place.
