Like when things like this happen
"The previously undiscovered asteroid came within 8,700miles of Earth but astronomers noticed it only 15 hours before it made its closest approach.
Its orbit brought it 30 times nearer than the Moon, which is 250,000 miles away."
That's quite close
"The tumbling rock was only 23ft across. Similar sized objects pass by this close to Earth about twice a year and impact on the planet about once every five years.
Astronomers believe the object, called 2009 VA, would have almost completely burned up while entering Earth's atmosphere, causing a brilliant fireball in the sky but no major damage to the surface."Those shooting stars are amazing.
"The Nasa NEO programme aims to detect and track at least 90 per cent of the 1,000 asteroids and comets that approach Earth and are larger than 0.6miles in diameter, by 2020.
They monitored a 100ft asteroid that whizzed 45,000 miles above the Earth's surface on March 2 this year. A similar sized object slammed into Tunguska, Siberia in 1908. The impact created a blast so powerful it levelled 1,200 square miles of forest."It is important to recognise our similarities - the places where we are the same. One of those places is our utter dependence upon mother earth. And our utter vulnerability. We are all alike in that place.
