You have reached the main content region of the page.

Explore the dwarf planet Pluto and its neighbours in the Kuiper belt as we search for a true Ninth Planet.

See the remarkably bright Eris, the spinning egg Haumea, and Sedna, whose orbit takes it deep into the far reaches of the Solar System. Is there a new planet beyond even these distant objects?

Using theoretical predictions and high-powered telescopes, scientists are uncovering hidden secrets about how our Solar System formed—and what it may still be hiding.
