Since Pluto was downgraded to a dwarf planet, this object on the outskirts of our Solar System has continued to fascinate astronomers. The New Horizons probe flyby in 2015 revealed a world far more complex than anyone had expected and offered a new perspective on other objects near Pluto, in the Kuiper belt.

The study of these objects with such magical names - Eris, Sedna, Haumea and many more – suggests that there may be a new planet hidden beyond the Kuiper belt. Follow Mike Brown and his team of three fellow Californian astronomers as they search for this ninth planet!
