It's 1.7 miles long. Its surface is covered in a sticky black substance similar to the gunk at the bottom of a barbecue. If it impacted Earth it would probably result in global extinction. Good thing it is just making a flyby.

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




Dark, massive asteroid to fly by Earth on May 31



NASA, better monitor this one.

I wonder how long till it does hit us . I hope someone is thinking about what to do when it finally is on a collision course , the orbit makes it look like it will some day ?

It will miss, but fairly close in space terms.

Its been known about for 15 years. 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 powerful radar antennas to see features as small as 12 feet across.

Yes Chris I know it will miss this time .

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

Close call: Massive two-mile-wide asteroid will miss Earth, according to NASA


It’s another close call.

NASA scientists say an asteroid nearly 2 miles in length will pass by the Earth on May 31. While it won’t be visible to the naked eye or amateur astronomers, its 3.6 million mile distance from the Earth qualifies as a relatively near approach.

One day a asteroid or comet, will hit us.

Update:


Asteroid 1998 QE2 to Sail Past Earth Nine Times Larger Than Cruise Ship


On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) -- or larger -- radar telescope at their disposal.

Glenn, I'll be dead and buried when Apophis, comes around.

Asteroid fly-by on Friday sparks debate over readiness for ‘Armageddon’-style event


The passage close to Earth of a mountain-sized asteroid expected Friday has reignited discussions among scientists about how to deal with the improbable — but definitely possible — circumstance of an asteroid predicted to hit the planet.

1998 QE2, as the asteroid is designated, will pass Earth at what NASA calls a “safe distance” of about 3.6 million miles — 15 times the distance to the moon, but nonetheless a near miss in astronomical terms — at just before 5 p.m. Eastern on Friday.

Question. Does a pass this close alter the trajectory of the asteroid with either the possibility of a closer pass next time or a new trajectory that does not cross earth's path?

NASA Radar Reveals Asteroid Has Its Own Moon


PASADENA, Calif. -- A sequence of radar images of asteroid 1998 QE2 was obtained on the evening of May 29, 2013, by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., when the asteroid was about 3.75 million miles (6 million kilometers) from Earth, which is 15.6 lunar distances.

The small moving white dot is the moon, or satellite, orbiting asteroid 1998 QE2.

It maybe gone but I bet there'll be plenty still watching it to see how our gravity has affected its trajectory.

Cheers.

Give them a couple of weeks and then we will probably see and watch and read some more about it .......

You never know Lynn we both mite live long enough to see Apophis come round the first time , everyone will be watching that one I expect .

After this, asteroid 1998 QE2 will hurtle back out into deep space; Friday's visit will be its closest approach for at least two centuries.


Not quite sure about the "superior" comment, but no doubt we will be enlightened in due course :-)
