Planet Nine
In July 2015, the New Horizons spacecraft gave us our first close look at Pluto, the most famous dwarf planet in the outskirts of our Solar System. The flyby was big news, and the data sent back to Earth revealed a world far more complex than anyone realized. Are there more worlds out there, beyond Pluto? What might such a world be like?
Planet Nine tells a tale of the search for another world hidden in the darkness.
Planetary scientist-explorers continually make discoveries about conditions “out there”. Planet Nine follows Mike Brown and his team at CalTech as they uncover new worlds such as the remarkably bright Eris; tumbling Haumea, an egg-shaped object rotating incredibly fast; 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?
