Big time! Every day roughly a hundred tons of meteoroids enter Earth’s atmosphere. Most of these things don’t present a danger but every now and then a huge one, like the one that hit Earth around Chelyabinsk, Russia can cause incredible damage.
Obviously all it takes is one impact from one large object and the entire surface of the Earth could be liquified into roiling oceans of lava. Some of the fragments of Earth thrown into the air and space will have been superheated into fragments of glass which would then rain down all over the Earth.
Nothing like this has happened for a long time but remember… it only takes one…
Which is why everyone should support the Planetary Society’s effort to create a grant for astronomers that will fund a search for dangerous Near Earth Objects (NEOs). If we’re successful then everyone on Earth will benefit from this early-warning system. If we know there’s something out there coming towards us soon enough, we can do something about it! :)
