An asteroid is due to pass by Earth on October 31 and miss us by a whisker, according to Nasa. Well, if whiskers were 499,000km wide, at any rate.The asteroid was spotted by Nasa a fortnight ago and is set to fly past the Earth on Halloween at over 125,000km/h.It will cross by Earth at the closest it's been since 2006.The space agency explained why they spotted it at such short notice.They said: "The asteroid is on an extremely eccentric and high-inclination orbit. "We won't be able to see the asteroid with the naked eye, but anyone with a telescope will be able to."This is the closest approach by a known object this large until 1999 AN10 approaches within one lunar distance in August 2027," said Nasa.The space agency has described the asteroid as "hazardous" as it falls well within the 7360000km threshold of proximity to Earth.The orbit is also erratic, so we can't exactly tell where it will go. However, despite this, Nasa is confident that it will not hit us.This probably won't spell the end of the world, but it is quite interesting.This news comes after a Christian group predicted the end of the world at the same time as an asteroid nearly grazed our little green planet.On October 10, asteroid 86,666 (2000 FL 10) passed safely by Earth and was considered a near-miss at a distance of 2,4000,000km away.This asteroid will come even closer than that one, but there is still no real need to worry. ..
