Get involved in Planetary Defense and help defend our planet!

Planetary Defense entails detecting, monitoring, understanding, and mitigating near-Earth objects. They are small objects in our solar system like asteroids and comets that come close to Earth. For the near-Earth objects that may impact Earth, Planetary Defense involves preventing or mitigating their impact.

In 1908, a large explosion occurred near the Podkamennaya Tunguska River in Russia, which flattened 830 square miles (2,150 square kilometers) of forest. It is referred to as the Tunguska event, the largest impact event on Earth in recorded history. A more recent impact occurred in 2013, where an asteroid exploded over Chelyabinsk, Russia. It is known as the third largest impact event in recorded history.
In the rare event that a near-Earth object hits Earth, we need to be prepared to prevent it from happening or mitigate its impact. This doesn’t mean you should start worrying – there is a network of organizations and projects currently studying near-Earth objects and working on prevention efforts, including Unistellar!
Now, because of the Unistellar eVscope’s breakthrough technology and ease of use, you can join professional astronomers and participate in the search and discovery of these objects, while defending our planet!
To get started, we recommend you read the following pages:
  • 1.) What is Planetary Defense? –> to learn about near-Earth objects, how they are found, and the ongoing efforts to defend our planet

  • 2.) How to? –> to learn how to observe Planetary Defense targets with your Unistellar eVscope

  • 3.) Planetary Defense Campaign –> for the most up-to-date Planetary Defense targets

  • 4.) Results –> to see the most exciting results from our Planetary Defense citizen science network

Happy Observing, Defenders of the Earth!
