... The chances of the Earth being hit by a comet from beyond Pluto — А la Armageddon — are much lower than previously thought, according to new research by an ANU astronomer. ... I calculate that small comets, capable of destroying a city, only hit the Earth once every 40 million years or so,” Dr Francis said. ... But asteroids and short-period comets come past again and again, so if we’re clever enough we can find them all and predict which, if any, will hit the Earth,” said Dr Francis. ...
