Are we safe (from Meteorites)?

Meteorite? It sounds so distant to us! Many of us heard about meteorite. But what's 'closer' to us are terms like "shooting stars" across the skies where people start making wishes that hopefully would come true! But hardly, we come across "real" news on this hitting the earth, until the recent Meteor strike in Russia, a huge one that's so impactful and caused worldwide attention!

So, what's meteorite? In fact, one of the articles reported the 'difference' in the use of terms like meteorite, meteor, etc. A check at wikipedia ( says...
"A meteorite is a meteoroid (a solid piece of debris from such sources as asteroids or comets) originating in outer space that survives impact with the Earth's surface. A meteorite's size can range from small to extremely large. Most meteorites derive from small astronomical objects called meteoroids, but they are also sometimes produced by impacts of asteroids. When a meteoroid enters the atmosphere, frictional, pressure, and chemical interactions with the atmospheric gasses cause the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting/falling star."
This is really interesting... the link shows a map that maps out the places on earth that have been hit by meteors. By zooming into the Asia region, actually, it seems like Singapore is pretty "safe" from such 'hits' (of course, that also means people in Singapore would hardly get the chance to make a wish before the shooting star! Haha).

On the other hand, does it also imply the chances of being 'hit' is relative to the size of land that each country has? What do you think?
