Asteroid 1998 QE2 will make its closest pass to Earth on May 31 at 1:59 p.m. PDT.X The space rock's name is not an homage to England's Queen Elizabeth II, or to the famous 12-deck ocean liner that was retired from service in 2008. It's just the moniker assigned by the Minor Planet Center in Cambridge, Mass., which names each new found asteroid according to an established alphanumeric scheme that lays out when it was discovered.
Scientists are not sure where this unusually large space rock, which was discovered 15 years ago, originated from. But the mysterious sooty substance on its surface could indicate it may be the result of a comet that flew too close to the sun, said Amy Mainzer, who tracks near-Earth objects at Jet Propulsion Laboratory in La Cañada Flintridge. It might also have leaked out of the asteroid belt between the orbits of Mars and Jupiter, she said.
We will know more after the asteroid zips closer to Earth and scientists using the Deep Space Network antenna in Goldstone, Calif., and the Arecibo Observatory in Puerto Rico can get a better look at it. Astronomers at both observatories plan to track it closely from May 30 to June 9, according to a JPL release.
At its closest approach the asteroid will still be 3.6 million miles from our planet (about 15 times the distance between the Earth and the moon), but it will be close enough for these powerful radar antennas to see features as small as 12 feet across.
"With radar we can transform an object from a point of light into a small world with its own characteristics," Lance Benner, JPL's principal investigator for Goldstone radar observations, said in a statement.
NASA leads the global effort to identify potentially dangerous asteroids. Our planet has been pummeled by space rocks throughout its 4.5-billion-year history, and more strikes are in our future.
The planet got a dramatic reminder of this reality this past Feb. 15. On that day, a 55-foot (17 m) object exploded without warning over Russia, just hours before the 130-foot asteroid 2012 DA14 gave Earth a close shave, missing our planet by just 17,200 miles (27,000 km).
There is no chance that asteroid 1998 QE2 could collide with Earth this go-around, and its next close approach won't be until 2119.
Still, Mainzer said the size of the asteroid, and its potential for mass destruction, should remind us that there are some scary things flying around in space.
"This is a really big asteroid, similar in size to the one that killed off the dinosaurs, and it's getting very close to us," she said. "Fortunately we've been tracking its orbit very carefully so we know with great certainty it won't hit us.
"We don't need to panic, but we do need to pay attention," she said.

makes you wonder if they are telling us about this asteroid if there are 10 more or so that they are keeping under wraps... wasn't it in the month of May that nostradamus warned us of something that will be on a global scale ?
ReplyDeleteCaveman you have a good point,in one of tose conferences with the government they already admitted to only being able to spot a small percentage of asteroids, so it's a scary prospect to think if one is a few are heading under the radar then we are over. Seems like it's been very active lately!
ReplyDeleteYes that's right and now that the big explosion beside the hospital in Libya has happened, and now even more promises will be kept. You already have his love ,now you just have to love him back. Much Peace and Prayers everyone... :)
ReplyDeleteScary shit man
