Apophis asteroid (named after the Egyptian god of darkness and destruction because scientists are eternal optimists) will be a close call with Earth in 2036. On a Friday the 13th. (really) The thing is 1,000 feet across, which isn't civilization ending but would kill billions (starvation mostly) and dominate the news for a few generations. Even Rand Paul wouldn't dare compare any subsequent event to a 1,000 foot diameter asteroid strike.
For those who prefer to look on the bright-side... it would stop global warming in its tracks, inaugurating a multi-year winter.
The thing is not expected to hit us, but is expected to come within 18,000 milescloser than some of our satellites. The moon averages about 240,000 miles distance, so we are talking about 13th of that distance. Or, another way, the Earth is about 8,000 miles diameter... so a miss of 2.25 Earth widths.
This Earth-Moon picture is to scale, from wikipedia. Apophis will come closer to Earth than the length of the word wikipedia. (In my browser)
But if Apophis comes near another objects or objects on its journey a slight deflection could make it a 36,000 mile miss or a 0 mile miss. (aka a hit)
Question: If we find out in 2015 that the asteroid has deflected and is 50%-50% to hit Earth in 2036, what year will we start taking it seriously?
a) 2035
b) 2036
c) 2037
d) 2038

(12,751 posts)with even the luckiest boxer eventually, and one of those blows connects. Let's hope earth advances technologically enough to first detect and then deflect or destroy one of these things before our luck finally runs out.

(24,370 posts)That answered the question " why doesn't the Earth look more like the moon with all of its craters?"
Two reasons. Weather and thus erosion and Jupiter.
Jupiter has acted like the Solar Systems giant vacuum cleaner for billions of years. The reason we don't get hit very often anymore is because of Jupiter.
I thought that was interesting.

(10,960 posts)That's not the same thing as saying ancient Mayan mystics predicted something.
18,000 miles is a rounding error.
It is not predicted to hit, but everything we know about the universe predicts it will be a ridiculously close call.

One of my favorite books as a kid was Lucifer's Hammer. Maybe I need to dig it out.

(10,960 posts)I loved that book as a kid, and enjoyed it a year or two ago as an adult, but the Niven/Pournelle wing-nut vibe diminished my adult enjoyment.
As a kid my favorite author in the world was Heinlein. Today I can't read him. It's like Glen Beck with a higher IQ.
Such is life.

(40,416 posts)Astronomers do not answer to government, any government!
There's no way to keep near Earth asteroid orbital parameters secret since those very parameters exist only because astronomers share data. Plus, anybody who can do orbital mechanics calculations can find out if the damned thing is going to hit.
This stuff may be rocket surgery, but it's not secret, nor could it be kept secret.
The SETI astronomer, Seth Shostak says that the last time they had a strong candidate for ET calling the New York Times contacted him and he never heard from anybody in government.
Something tells me that if astronomers see a chance that an asteroid would hit, they'd have to go to Congress with hat in hand before anybody in government would pay attention. Even then, they'd have a bunch of Congress critters claiming it's bunkum and Michelle Bachmann would be saying, "Good! That means Jesus is coming back."

(3,539 posts)Would we cower in fear?
Would some among us destroy the rest trying to have those "last good times"?
Would we combine resources in an actual attempt to send "Aerosmith and Bruce Willis up to fix it"?
Would the 2035 equivalents of John Boehner and Mich McConnell block any attempt (in typical republican fashion) to do anything? Anything at all?
So... So you think you can tell.....

(10,960 posts)We know these things with terrific precision assuming nothing changes. On the Newtonian side of things we are rock solid.
We do not, however, know everything the asteroid might experience in its travels. We are not even aware of all matter it will encounter. So we can estimate, but we do not know.
It is unlikely to hit us. Even exceedingly unkely to hit us.
But it is still precisely what the OP says it is, 1) the greatest asteroid threat we have ever discovered, and 2) unlikely to hit us.

(4,062 posts)Apophis was yesterday's news as far as threat goes. In fact, the only time we thought it posed a significant risk was back in 2004. The 2036 impact was never particularly likely, but after all the press it was worth beating down the uncertainties. And the only remaining concern about that was removed by the Goldstone observations last month.
As far as the greatest CURRENT asteroid risk, that is 2007 VK184 hands down and that is only a "1" on the Torino scale (in other words, nothing to get to worked up about either).

(44,173 posts)Would that still cause some collateral damage? Yes, but that is far preferable to a near ELE.

(28,749 posts)We will talk about it years in advance... then put it off.
We might come up with an arbitrary deadline a few months in advance... then put it off.
Then the networks will come up with graphics...
Then it will become a serious issue...
But only then.
Although we might still put if off...
