Rocks in the Sky

After a meteorite hit Chelyabinsk in Russia last week, there has been a lot of confusion around those stones falling from space. Specifically, how do you call them? What are the differences? This is a great summary by narwhal creative.


  • Comet – a rock originally from the outside of our Solar system
  • Asteroid – a rock from the Solar system, can be bounced towards Earth
  • Meteoroid – a space rock smaller than an asteroid
  • Meteor – this is not a rock, but the streak of light caused by an asteroid burning in our atmosphere
  • Meteorite – this is an asteroid or meteoroid that actually hit the ground

So, to sum it up, an asteroid causes a meteor when it burns in the atmosphere, and if it doesn’t burn completely and strikes the ground, it becomes a meteorite.
