Well, if this object is what i think it is (Niburu), it is approximately 4 times the size of Jupiter...

yes, i assume it is. what i said in the op is what my source told me. thats all. i'm not an expert on any of this. i'm presenting you with what i know.
"YOU know about the comet elenin?!?, nasa is worried it will hit the space station"

If thats the case then the space station is not the only thing that needs to be concerned. That is approaching commercial airline traffic !!!

Here's the math: 92,955,807 miles (1au) * 0.0004617 = 42917.6960919 miles.

That is still more than 42,000 miles out from the Space Station...
Comet C/2010 X1 (Elenin) is a long-period comet discovered by Russian astronomer Leonid Elenin on December 10, 2010 at the International Scientific Optical Network's robotic observatory near Mayhill, New Mexico, U.S.A. At the time of discovery Elenin had an apparent magnitude of 19.5,[2] making it about 150,000 times fainter than the naked eye magnitude of 6.5.[5] The discoverer, Leonid Elenin, estimates that the comet nucleus is 3–4 km in diameter.[6] As of April 2011, the comet is around magnitude 15 (roughly the brightness of Pluto), and the coma (expanding tenuous dust atmosphere) of the comet is estimated to be about 80,000 km in diameter.

News reports had warned sky watchers in advance: On Nov. 18, 2001, Earth was due to plow through a minefield of debris shed by Comet Tempel-Tuttle. Innumerable bits of comet dust would become meteors when they hit Earth's atmosphere at 144,000 mph. Experts predicted an unforgettable display ... and it came.
Millions of people saw the show, but only three of them -- the ones on board the space station -- saw it from above. "We had to look down to see the meteors," says Culbertson. "That's because the atmosphere (where comet dust burns up) is below the station."
"A typical Leonid disintegrates about 100 km above Earth's surface," explains NASA scientist Rob Suggs. "The ISS is much higher than that. The station (like the space shuttle) orbits our planet at an altitude of about 350 km." Suggs is the leader of the Space Environments group at the Marshall Space Flight Center; he helped organize the crew's observations of the Leonids.
