Here it comes, tin hat time

I thought that there was an international treaty so that no war ship could weigh more than 50 million tonnes?

no aliens signed up as far as i know

Not sure on that, but if it's the case it could be the unladen displacement that can't be more than 50 million kg ( 50,000 tonnes)?

The asteroid's relativistic mass increases with velocity.

[outragous76]

Surely the asteroids biggest effect will be impact?

Not when it misses.

The White House normally ignores questions about aliens making contact with the Earth.

 But they have just made a public announcement that they are Not in contact with any Aliens, hmmmm

Also why has the now privately funded Seti been put on standby

[zerofive]

At least I won't be the only one missing the world recently.

LOL - nh sir.

The effect of the small object on the larger is tiny, but it's still there. The earth, for example, is 0.000 003 Solar Masses, but it still has an effect on the Sun's position and velocity.
When you're looking for earth-like planets orbiting other stars, you can't see them directly, they are way too small. All you have to go on is that tiny wibble in the star's position.
If you stand on the top of St Paul's, and I stand at Heathrow holding up a coin, you would have to be able to measure the distance between the Queen's nose and her eyebrow on the coin, that's the kind of measurement we're talking.

Like I said, when it's at its closest to the moon as it travels on its course, the effect on the moon's orbit will be less than 500 nanometres. 

500nm = 0.0000005m = 0.0005mm

In real terms = zero.

Point taken, but why would God send them if they have no effect? Is this one a warning?

Should be interesting to see the footage of this.

With regards to the whole danger, asteroid, end of the world stuff; if there was a planet killer just days away from hitting the Earth would you want to know?

He's just a crap shot.

It'll be visible in the night sky with a basic telescope.  Nothing too exciting, and Bruce Willis won't be needed.
