Humans needed to find Planet 9 - Deep Space Drones
The Australian National University (ANU) is looking for people to help find the elusive planet 9.
Although there was a ninth planet discovered in 1930, it has been since then demoted to a dwarf planet.
This new hypothetical planet 9 could be a Super Earth, about ten times more massive. It would be somewhere between two to four time the diameter of the Earth.
