London - The Astronomers were doubtful that the asteroid could hit the Earth in 2029 and the people felt panicky. They felt that 2004 MN4 had a 1-in-40 chance of a collision on Friday, April 13, 2029.

The Astronomers gave it a rating of 4 on the 1-10 Torino scale used to gauge the threats posed by asteroids and comets.

The asteroid is estimated to be about 1,400 feet (430 meters) long. Though that's not large enough to create a mass-extinction event, some scientists compared to the demise of the dinosaurs 65 million years ago.

Dr. Raj Baldev, Cosmo Theorist from India has a different opinion, he said, "The asteroid loses its size during its travel and it could not sustain the original length of 430 meters while crossing nearer to the Earth." But if the asteroid were to hit the wrong place at the wrong time, it could cause a giant tsunami wave or deliver a nuclear-scale blast.

Fortunately, the alert led astronomers to check their archives for images of the asteroid that might have gone unnoticed at the time.

Guided by the latest data about 2004 MN4's orbit, the Arizona-based Spacewatch Project spotted the rock on five images made back on March 15, said Donald Yeomans, Manager of the Near Earth Object Program.
