They crossed vast reaches of space in a journey lasting thousands of years before reaching their target where they attacked the first planet they encountered, Earth. Due to a terrible miscalculation of scale the entire battle fleet was swallowed by a small dog.
It Maksutov to top these comments...
Here’s an interesting paper on NEA mining. (I apologize if it’s old news to you).
http://www.esm.vt.edu/~sdross/papers/ross-asteroid-mining-2001.pdf
you could give a large chunk of the artic to the first country
that blasts it out of orbit as it approaches gore-earth.
Point taken, NEA impacts kids and the other the Earth. Both potential disasters.
Thank you! Thank you! Thank you!
This is exactly what I’m talking about; it solves more than just one problem, and much of the work in space can be done by robots using solar or nuclear power for energy. Since humans wouldn’t need to be there, life support systems wouldn’t be necessary. From mining to smelting, all work would be done remotely by robots.
We’re talking about rocks here, folks; where time, and the need of a speedy of return isn’t of necessity. So it is possible to utilyze gravity wells of larger planetary bodies for energy, computing sling-shot orbits for sending ore trains towards Earth or moon orbit. Processing metals in space means stronger metals - zero gravity and in a vacuum - and who need cares about environmental hazards!
I think under the same conditions, it would play just like global warming. The media has the sheeple in this country conditioned that everything is doom and gloom.
"The object was long recognized to be dangerous, but we didn't know where it was," says Jenniskens. "Now it is no longer just out there."Alright! I've been hopin' something exciting would happen! Thanks Blam for the prodigal stone topic!

Radioastronomy is important in both.
"This is a now-dormant comet nucleus, a fragment of a bigger object that, after breaking up in the not-so-distant past, may have caused the gamma Piscid shower of slow meteors (IAU #236) that is active in mid-October and early November," he says. 2007 RR9 moves in a 4.70-year orbit, nearly all the way out to the distance of Jupiter. Because of this elongated orbit, it has a Tisserand parameter of T = 2.94, which defines it dynamically as a Jupiter Family Comet (T = 2.0 - 3.0), not an asteroid (T > 3.0).
Who knows, some kind of information about this object may someday appear here:

“As the set of available observations for a given object grows we are often able to rule out previous potential impacts as no longer consistent with the observations. The following table gives a listing of such objects for which all previously detected potential impacts have been eliminated. Last Updated Oct 15, 2007”

Then I guess you’ll haveta walk the Planck...............
They run the orbits backwards. Gravitationally forced dynamics works as well with time running backwards as forwards. Then when two, or usually more, objects "come together" in reversed time, they rule that a either a collision or at least a strong gravitational interaction, which change orbits. They have to take into account the gravity of the Sun and the planets. Although they could ignore most all but Jupiter most of the time, unless the object gets "close" to some other object. Where "close" depends on the size of the other object.
Some of the people who do this work for a different division of my employer. See 'em on National Geographic, History Channel, etc, all the time.
Finally, a reason not to give a crap, kill me now
NOOOO! I JUST TURNED 21, DAMN!
HUH? I just planted my medicinal marijuana crop
I shoulda ended up at Kappa Alpha Theta
Thanks for that explanation. The universe is a pretty cool place, isn't it? I wish I understood more about it.
How the heck do you know what came from where in the first place?

Thanks for the answer.. but how do they know that they are looking at the same two objects over time? They do allude to that happening when more than two may be involved, pretty good science any way ya cut it.. ;-)
Big bright puffball Holmes is a comet like no other

Did anyone else watch the “End of the World” scenarios on the History channel yesterday?
I liked the frozen CO2 comet that caused massive global warming so severe that it killed the giant Koala bears that could eat a fully grown tree in the space of an hour and all his fellow denizens also falling victim as their overgrown bodies failed to adapt to the sudden loss of forage.
How long does it take Eucalyptus to reach maturity, anybody know?
The impact sent up such a cloud of CO2 gas, dirt, debris and smoke that the temperature increased over 10F in less than a decade as the dense greenhouse air wouldn’t allow a bit of heat to escape to space.
That’s what they said.
