Did you know that the highest graveyard in the world is actually in orbit around the Earth? Located about 36,000km above the surface of our planet, this "graveyard" is actually an orbit where old satellites are pushed, in order to avoid collisions with satellites that are functional. Other satellites that aren't orbiting at high enough altitudes are sent back to the Earth's surface instead - find out what happens to these satellites on this week's episode of Gadgets 360 With Technical Guruji.
