Planet Nine

Planet Nine

In 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 pictures sent back to Earth reveal a world far more complex than anyone realized. Now scientists are making new discoveries about our Solar System—and what it may be hiding: an object 10 times more massive than Earth far beyond the orbit of Neptune. Follow astronomer Mike Brown and his team as they uncover dwarf worlds like the remarkably bright Eris, egg-shaped Haumea and Sedna, whose orbit takes it deep into the far reaches of the Solar System. Is there a new planet beyond these distant objects? We’ll tag along on Brown’s first night searching for a true ninth planet at the Subaru Telescope in Hawaii. Join us on the hunt!

• Please note: Free ticket reservations are for one show at the date and time specified above. Seats are socially-distanced and cloth face coverings are required. For best seat selection, it's a good idea to arrive a little early. For the safety of our visitors and in order to prevent accidents, late entry is not allowed. Likewise, once a show has started, if you leave the planetarium for any reason, re-entry is not allowed due to safety regulations in the darkened environment.
