Leiden University's computer algorithm spots ELEVEN asteroids that could hit Earth

A computer algorithm from Leiden University in the Netherlands has spotted eleven asteroids that could eventually hit Earth and cause'unprecedented devastation'. All were missed by NASA software thanks to their chaotic orbits, which are difficult for current techniques to predict and identify as being potentially dangerous. Each are more than 328 feet (100 metres) in diameter and will pass closer to our planet than ten times the distance between the Earth and the moon. For comparison, the Tunguska object which flattened 772 square miles of forest in Siberia had a diameter of around 164–262 feet (50–80 metres). However, these space rocks won't pose a threat in our lifetime, however -- for they will only get worryingly near to Earth between the years 2131 and 2923.
