OF THE
TIMES
Every day, Earth is bombarded with more than 100 tons of dust and sand-sized particles.
About once a year, an automobile-sized asteroid hits Earth's atmosphere, creates an impressive fireball, and burns up before reaching the surface.
Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area.
Only once every few million years, an object large enough to threaten Earth's civilization comes along. Impact craters on Earth, the moon and other planetary bodies are evidence of these occurrences.
This is how big an asteroid would need to be to wipe out New York City https://t.co/M6xEc6b4ql pic.twitter.com/dHskCWts7T
