The Missing Planet – THE INCREDIBLE ADVENTURES OF THE HERA MISSION

‘The Curious Case of the Missing Planet, the second episode of the cartoon series The Incredible Adventures of the Hera Mission, tells the story of the discovery of asteroids. Astronomers in the 18th century were sure there was a planet in the wide gap between Mars and Jupiter – and even formed a group called the Celestial Police to find it. But eventually it became clear there was no single world out there, just lots and lots of little ones. Fast forward to today and more than a million asteroids have been discovered, and Hera will perform close-up detection on two of them.

Join our intrepid heroes Hera the Asteroid Detective, Milani the Rock Decoder, Juventas the Radar Visionary, Didymos the Ancient Traveller and Dimorphos the Mighty moon for another incredible adventure.
