Asteroid 1998 QE2 will make its closest pass to Earth on May 31 at 1:59 p.m. PDT.
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.

John von Radowitz
Saturday 18 May 2013
An asteroid nine times larger than the QE2 is due to sail past the Earth later this month.
Luckily, the giant space rock will get no closer than 3.6 million miles, or 15 times the distance between the Earth and the moon.
Coincidentally, scientists have named the asteroid 1998 QE2. The name has nothing to do with the transatlantic Cunard liner - it follows a code used for newly-discovered asteroids by the US Minor Planet Centre in Cambridge, Massachusetts.
The asteroid is believed to be about 1.7 miles long, or nine times the length of the Queen Elizabeth 2 ship.
It was discovered on August 19, 1998, by the Massachusetts Institute of Technology Lincoln Near Earth Asteroid Research (Linear) programme near Socorro, New Mexico.
The object makes its closest approach to Earth at 9.59pm, UK time, on May 31.

I doubt it because it's black, small, and too far away, but you never know if conditions might be just right...

So maybe 1000 times the volume and 5-10,000 times the mass.

(10,745 posts)My curiosity has been piqued, though: what is so special about this gunk on the asteroid that it would cause global extinction if it were to land versus just massive amounts of destruction?(or am I reading this wrong?)

The black tarry gunk only serves to identify what type of rock it is.
