[Cnet] Giant asteroid to get closer than moon

post #1 of 110
Thread Starter 
Quote:
An asteroid the size of an aircraft carrier is sailing toward Earth, NASA says.
Never fear, however. The space agency says that although next week's flyby of Asteroid 2005 YU55 will bring the rock closer to our home planet than even the moon gets, the asteroid will cruise safely past, leaving in its wake not destruction but data.

Quote:
The agency has already begun using radio waves to scan the 1,300-foot-wide space rock, which will get closest to Earth on Tuesday at about 3:30 p.m. PT
Quote:
An extraterrestrial rock hasn't come this close to Earth since 1976, and we won't witness another such close encounter till 2028, NASA says. YU55 itself hasn't come this near for 200 years. Amateur astronomers who want to check it out for themselves will need a telescope with an aperture of 6 inches or larger, the agency says.

I love articles like these because they remind me about how crazy the universe is.

Seems like something some people here might be interested in watching as well.

That is blatantly wrong. The Earth is hit by extraterrestrial rocks multiple times a day. Many more burn up in the atmosphere.

Will we be able to see it with nothing but our eyes?

I believe it meant one of this magnitude hasn't.

Yes, I've read that thank you, but I suppose that's if they want to see it in detail?
What I mean is, will we be able to spot it on the sky with our eyes?

Did you read it?

EDIT: Just saw the other post. I don't think you will be able to see it without a telescope.

I wonder if it was actually going to hit the earth:
- Would they tell us?
- Would they even be able to stop it?

A astroid this size would wipe out all/majority of life if I remember the research I did on this a few years back.

EDIT: I was far off.

Here's the results:
Transient Crater Diameter: 7.23 km ( = 4.49 miles )
Transient Crater Depth: 2.56 km ( = 1.59 miles )
Final Crater Diameter: 9.4 km ( = 5.84 miles )
Final Crater Depth: 581 meters ( = 1910 feet )

We talked about this in my college Astronamy class back in 2006. My professor stated that if the thing deviated just 3° due to some unforseen gravitational pull, or a collision during it's long orbit, it could be devistating. I'm not saying it is the end of the world, but the fact that there is no certainty is the hallmark of like on this planet. I thought it was passing by though in 2029. But I guess it is going to pass by in 2028.
