Comets flyby 2016: 2 comets to flyby earth, does the earth faces any threat 

Two comets are going to pass through our planet earth one after the other today and tomorrow. This is an event that is not just rare, but comes in hundreds of years. The close flyby, according to NASA is happening after more than 250 years.

It must be kept in mind that we didn’t had much developed technology even a hundred years ago to keep an eye of, let alone be truly sure as to when such incident happened in the past. So this might have happened even earlier than NASA says right now.

NASA has said that two comets are heading towards earth today and tomorrow. The bigger of the two comets namely 252P/LINEAR, is about 750 feet in size and surrounded by an emerald green cloud of gas. It is expected to make its closest approach to our planet on March 21 at 5:14 a.m. PDT.

Rosetta cometThe massive comet will pass through the planet earth by around 3.3 million miles. This is a very long distance by any means and NASA has said that it will be around 14 times farther from our planet than the moon on March 21.

Nonetheless it is not the closest. On March 22, another comet P/2016 BA14 is all set to fly by the earth much closer than its twin comet. NASA says that P/2016 BA14 will come visiting us from a distance of 2.2 million miles of our planet. This will be 9.2 times farther from the Earth than the moon. The planet will be closest to planet earth at 7:30 a.m. PDT.

While talking about it, Paul Chodas, manager at NASA’s Center for Near-Earth Objects, said the comets do not threaten Earth, rather the fly-bys are “an excellent opportunity for scientific advancement on the study of comets.” The comets are comparatively dim, given their small size of a few hundred feet in diameter. Both will pass over the Southern Hemisphere.
