Asteroid Apophis 500 meters in diameter to ram into Earth in 2029
Asteroid MN4 otherwise known as Apophis has been designated the most dangerous heavenly body of the century
On April 13th, 2029, the asteroid may crush into Earth causing an explosion 100 times bigger than the blast of the A-bomb dropped on Hiroshima in 1945. A large part of Moscow is likely to disappear.
Apophis was discovered by Steve Chesley at NASA in June 2004. He stirred up a lot a buzz among his colleagues by saying that the thing is definitely going to ram into Earth. The colleagues rushed to telescopes and checked the photographs of the celestial sky. They found the asteroid on a photograph taken back in March.
The diameter of MN4 was initially measured at 500 meters. Researchers reduced the diameter to 320 meters after conducting a series of additional calculations. The asteroid rotates once in every 323 days, it crosses Earth's orbit twice a year. There is a real threat of collision, but it is not so deadly as previously thought. The asteroid will not be smashing our planet on April 13th, 2029. But it is expected to cross the sky in a really close vicinity to Earth. It might as well destroy a communications satellite.
Friday the 13th: not so unlucky after all?

Back around Christmas, near-Earth asteroid astronomers were talking about asteroid 2004 MN4. It was calculated to have a 1 in 60 chance of hitting the Earth on Friday April 13th, 2029. A week or two later the chance of impact was reduced to zero after some more orbital data was recovered.
Still, it will be a pretty close shave. The 320 meter-wide rock will pass closer to the Earth than geosynchronous satellites orbit. It will be a 3rd magnitude naked eye object skimming across the night sky.
Were this asteroid to ever actually hit the Earth, it would devestate a land area the size of Texas. An ocean impact would make the Christmas Indian Ocean tsunami look like waves in a bathtub.
Friday the 13th should lose its bad reputaion. We're all going to be very lucky on that day.
