An asteroid, which is believed to be on a collision course with Mars, will not affect the Earth if it hits the 'Red' planet in January 2008, a Russian Academy of Science spokesman said.
Sergei Smirnov said the explosion could be on a scale equal to the Tunguska event, when a meteorite, which crashed into central Siberia in 1908 caused destruction on a nuclear scale. The enigma still thrills scientists all over the world.
