Comet Elenin Will Not Wreak Havoc Upon Earth: NASA

NASA said the 3-5 kilometer-wide comet Elenin will not wreak havoc upon our Earth. The space agency said that it is too small to do so, and that its "closest approach" to Earth will bring it 90 times the Earth-moon distance.

NASA decided to hold a Q&A session headed by Don Yeomans of NASA's Near-Earth Object Program Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and David Morrison of the NASA Astrobiology Institute at the NASA Ames Research Center in Moffett Field, Calif. in order to allay any fears of worst-case scenarios.

"So you've got a modest-sized icy dirtball that is getting no closer than 35 million kilometers," Yeomans said, according to Discovery News. "It will have an immeasurably minuscule influence on our planet. By comparison, my subcompact automobile exerts a greater influence on the ocean's tides than comet Elenin ever will."

A "marauding brown dwarf doomsday theory" has reared itself again, jumping on its earliest opportunity. Many doomsday theorists said that a brown dwarf is proof of impending doom and that it can have a huge gravitational influence on our solar system.

"A comet is nothing like a brown dwarf. You are correct that the way astronomers measure the mass of one object is by its gravitational effect on another, but comets are far too small to have a measurable influence on anything," Morrison said, according to Discovery News.

"The truth is that Elenin has received much more attention than it deserves due to a variety of Internet postings that are untrue," Morrison added.
