Another asteroid discovered over the past few days is flying by the Earth at an extremely close distance as we speak - its name is 2010 WA and it has a diameter of just 3 to 6 metres, which is much too small to make it to the ground if it were to hit the planet. A quick stick man diagram will show just how small this is compared to a human:
In spite of the tiny size it's passing by at an extremely close distance (which is what makes it newsworthy), just 10% that from the Earth to the Moon. That's around the same altitude as a geostationary satellite.
