Are comets or asteroids more dangerous?

Answer 1

While asteroids and comets have different constitutions - asteroids are mostly metals and rocks while comets consist of water-ice, dust and rock - with comets potentially being potentially less dense, comets travel much faster than asteroids. An asteroid may travel upwards of 40,000 miles per hour, a comet travels over 150,000 miles per hour.

Answer 2

Because they're often unpredictable. A large enough asteroid striking the earth, could throw up enough material into the atmosphere to shut out the sun for years. This would all-but end all life on this planet ! Even a smaller asteroid could cause thousands of deaths if it struck a heavily-populated area.

Answer 3

Asteroids are generally considered more dangerous than comets because they are larger and potentially collide with Earth more frequently. However, both comets and asteroids have the potential to cause catastrophic damage if they were to impact our planet.
