Bedreigings vir Aarde: satelliete, asteroïede en meer …

Potentially hazardous near-earth objects are asteroids and other space debris within about 50 million km of earth that could be large enough to cause mass casualties and damage to the planet. Depending on their size, speed, angle and impact region, these objects could threaten billions of lives on impact and in the ensuing tsunamis, earthquakes, and fires. And then there’s space weather … Do we have ways of dealing with these threats?
