A routine discovery in which a pass near the Earth is predicted that poses no unusual level of danger. Current calculations show the chance of collision is extremely unlikely with no cause for public attention or public concern. New telescopic observations very likely will lead to re-assignment to Level 0.<!--QuoteEnd--></div><!--QuoteEEnd-->
So uhh, no, according to nasa it won't hit us.

I hate idiots who can't put up an accurate, descriptive topic title.

Every year the sun comes within 1 AU of hitting Earth. I think it's time to pack up and move to a less dangerous solar system...
I wonder if you could headbutt yourself in the posterior with enough force and speed to enter escape velocity through the resulting centrifugal forces.
<!--QuoteEnd--></div><!--QuoteEEnd-->
is that even possible? Can you cause centrifugal force on your own body as a system? Ugh, I dont even want to try and figure it out.
I suppose I should just find it funny and stop typing....

Have you ever tried lifting yourself up by the shirt? It works on the same principle of shifting center of gravities. If you do it just right, the earth's gravity is temporarily displaced. It's what allows double or even triple jumps in mid-air.

I hear you man, this place is a disaster waiting to happen.
its not like we've found anywhere else to live?

Well, you wouldn't enter escape velocity as you'd be spinning and not moving. You would need something to push off to do it though, if you were in free fall then you wouldn't be able to start spinning, unless you pushed off something or threw something etc.
I was just thinking about throwing a spanner in one direction and then entering escape velocity, you'd have to throw it so fast. Say a human is 80 KG and escape velocity is 7 miles per second. The spanner is probably 400g so you'd have to throw it at almost <a href="http://www.google.com/search?num=20&hl=en&lr=&q=7+miles+per+second+*+70+kgs+%2F+400+grams&btnG=Search" target="_blank">2 million meters/second.</a> Quite funny to think about!

When will vegas begin taking bets? With the odds that high you'll be rich if you bet the asteroid will hit and it does! Rich I tells ya! <b>RICH!</b>
Well remember guys, according to quatum theory there is always a chance we could all be made into cheese at any moment, ofcourse this is very unli-

Pfrlblbl. So what? The sun's big. Well, it's a reasonably small (but not noteworthy so) star, but big compared to our planet. Take a comparably small object, like, say, Jupiter. Even if you'd just move Jupiter anywhere NEAR our planet, the earth would tear apart due to tidal forces. And Jupiter has much less mass than Sol, so it's much easier to move. Not to mention the possibility of using a <a href="http://www.schlockmercenary.com/d/20030803.html" target="_blank">fusion candle.</a>

Someone draind the humor and satire out of NS when I wasn't looking, didn't they?
Based on the distance you actually put the Earth from Jupiter, it would most likely only result in overwhelming tidal forces that created continuous eruptions on the planet's surface, like Io.

Earth could probably be placed inside Callisto's orbit without much trouble...aside from dramatic climate shifts due to a likely synchronous orbit, stronger tidal forces, and potential distance from the sun (unless you moved Jupiter closer, but than gravitational interaction between the sun and Jupiter may have adverse effects)...among other things. I suppose it is possible the planet could fracture due to extreme tidal forces, but it's far more likely the friction and stress would simply liquify the planet, if it were placed too close to Jupiter.
I suppose the potential debate really relies on what you would define as 'near'; as in, do you consider 1,000,000km 'near' (about 1/150th of an AU)?
[edit] Of course, if you consider much less than that 'near' than you might as well throw Venus or Betelgeuse in Jupiter's place, because they'd probably have a similar effect on the planet (okay, well, maybe not Betelgeuse, the Earth would be cooked before it could be torn apart (if you could instantly teleport a star)). [/edit]
Anyway, that impact event isn't nearly big enough to cause an armageddon type event. Although I hate to resort to an unsourced wikipedia 'fact' "the body that caused the Chicxulub crater in Mexico is estimated to have released the equivalent of as much as 190,000 gigatons of TNT." Meaning the impact event in the Yucatan which is suspected of killing off the dinosaurs is susptected to have been 10,000x more powerful than this asteroid's potential (<a href="http://en.wikipedia.org/wiki/Gigaton" target="_blank">Wikipedia's gigaton</a>, also check out the Tunguska event, but I'm unable to find the energy output of it).
George Bush or evil, sentient blue whales are likely to be a greater threat to humanity and the world than that asteroid could ever hope to be (you know, if it ever became sentient - and also evil - and 'hoped' to destroy things).
