Today’s Video of the Day from the European Space Agency (ESA) describes the dynamics of near-earth asteroids, which are space objects comprised of rock and metal that shoot past our planet.
According to the ESA, there are over 18,000 known near-earth asteroids. Around 800 of these have no chance whatsoever of impacting the Earth, and the chance of a large asteroid striking our planet it is extremely unlikely.
The video is part of the the ESA’s Space in Videos series.
On June 29th and 30th, the ESA will host live webcasts for Asteroid Day 2018.
