The incredible adventures of the Hera mission | The curious case of the missing planet


Meet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth.

Suitable for kids and adults alike, this episode tells the story of the discovery of asteroids, in ‘The Curious Case of the Missing Planet’. 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.

  1. The European Space Agency the best!!!!!!!!🇧🇻🇨🇦🇪🇸🇩🇰🇨🇵🇬🇧🇬🇷🇭🇷🇮🇪🇱🇻🇱🇺🇷🇴🇸🇮🇸🇰🇧🇪🇫🇮🇪🇪🇮🇹🇳🇱🇵🇹

  2. Perhaps something like the formation of the Moon, after the collision of Earth with Teti, can explain the debrees, and Ceres could be simply what's left of the main planet after the collision, while solar gravity will do the rest, like it did with the Earth and the Moon. Earth and Moon are in fact just two asteroids, no matter we call them planets. Planets are a gigantic collection of asteroids smashed together and kept together by solar gravity since billions of years.
