An asteroid named Apophis has a 1 in 45,000 chance of striking Earth on April 13, 2036 and has shaken scientists to ask the UN for help in dealing with such an event.
Ex-astronaut, Rusty Schweickart, told an American Association for the Advancement of Science conference in San Francisco "It's not just Apophis we're looking at. Every country is at risk. We need a set of general principles to deal with this issue."
The president of Oregon-based Decision Research, a risk analysis organization, told reporters that the said asteroid could take out an entire city or region.
