Newly Discovered Asteroid Orbits Earth In Horseshoe Orbit
63 replies, posted
[QUOTE=ExplodingGuy;29066220]The reason why it maintains a horseshoe orbit, is as the object is moving away, it looses its momentum, gravity then pulls it back before it can complete a full circle, creating a horseshoe orbit. Its orbit grows in diameter as it accelerates, and decreases as it decelerates.

what the fuck
[quote]They found that all the clones remained in a so-called "horseshoe" state with respect to the Earth. [B]In this configuration, an object mimics very closely the orbital motion of our planet around the Sun[/B], but as seen from Earth [B]it appears[/B] to slowly trace out a horseshoe shape in space.[/quote]

[quote=wiki]The asteroid always orbits the sun in the same direction. However, it goes through a cycle of catching up with the Earth and falling behind, so that its movement relative to both the Sun and the Earth traces a shape like the outline of a horseshoe.[/quote]
What happens when it catches up?
[QUOTE=glennman94;29066262]Like it or not, there [b]is[/b] an asteroid out there with our name on it and it's heading for us right now.
That's a scary thought isn't it ?[/QUOTE]
Not really. Any asteroid that would hit us has already done so (with the exception of the possibility of an asteroid being knocked out the asteroid belt between us and mars, in which case there are very few large enough to cause enough devastation for another extinction). The asteroid with our name on it as you so put it, isn't within our solar system and could take millions of years to reach us.

It turns around and goes the other way.

[QUOTE=ExplodingGuy;29066220]The reason why it maintains a horseshoe orbit, is as the object is moving away, it looses its momentum, follows the outward accelerating force of earth's gravity. After it leaves the influences of the earth's gravity, the sun then pulls it back, creating a horseshoe orbit. Its orbit grows in diameter as it accelerates, and decreases as it decelerates.

I don't understand any of that..

So it speeds up and slows down when it gets to Earth? How the fuck?

It's pretty simple. The asteroid gets trapped between two gravimetric fields - the Sun being the stronger as it's curved by Earths, pulling it out of our own.
Interesting.
Praise Jesus he made the asteroid go the other way!

If it's been like this for thousands of years it's going to stay like that for thousands more. And if it for some reason it does threaten us when it's heading our way again(somewhere around 2200) then I'm sure by then we'll have the technology to deal with it.
I wonder whats chillin at our L3 point right now.
Here we are stuck on Earth, dealing with whatever the universe damn pleases to do!
Hey.
Asteroid.
FUCK YOU!!
Wow. I can't even fathom that.

Seriously, I like to think I have pretty good knowledge of physics and general sciences and such, especially for my age, but this goes over my head and then stabs me in the spinal cord.
MAGNETS. HOW DO THEY FUCKING WORK.
You know what's funny? If this hits something out in space, even something small, it can throw it off course just enough to send it all the way in next time around.
Same goes with any asteroid out in space. It's just a matter of time, and dumb luck that two will undoubtedly cross and knock the other one straight for us.
There is so many things out there, and we don't even know .001% of it. And by out there, I mean beyond our solar system. Think of all the crazy shit we'll find when we get there....

Reapers
The possibility of it crashing into earth = 0%
Messiah is riding his asteroid horse and is coming to save us 2012!!!! :downs:
[QUOTE=Ridge;29080272]Reapers[/QUOTE]
That's a possibility, either in this universe or one of the countless other versions of it.
In at least 1 of those versions, Facepunch is the government of the earth.
When we start colonising space i think we should prepare for a worst case/Reaperesque scenario, just incase something nasty as fuck rolls up into our system so we can blast it back into the stone age.
[QUOTE=Legend286;29058756]Asteroid is trolling earth, pretending to crash and then at the last moment turning around.[/QUOTE]
I was watching the gif and at around the 2004 point where the asteroid was getting close to Earth I had 2012 running through my head, but then it turned around.

Scary to think about.
Then again there's an alternate universe where facepunch is government of the earth, and is good at their job too :ohdear:

Wow, God is amazing!

Like it told before you said it. You're a genius.

Such a universe would be impossible, logically.
They are mutually exclusive qualities.
It is like saying there is a universe in which light and dark are the same thing. Impossible to exist, or at the least, impossible to conceptualize because in such a universe, the physical laws would be so vastly different.
[QUOTE=ewitwins;29063967]How is this even physically possible?[/QUOTE]
G O D!

that puts an end to end of earth via asteroid theory, thank fuck for that, see i ain't too fond of being squashed by a fucking flying rock

All I could infer from this is that it moves accordingly to our magnetosphere. That's still pretty fucked, but I would like it if you could elaborate.
