Asteroid 2005 YU55-November 9th 2011
Edited on Tue Nov-01-11 10:51 PM by FarLeftFist
The same day of the first Nationwide Test of the Emergency Alert System. Also I heard of some massive military training operation going on the day before in the pacific ocean Here's the link to the asteroid path: http://www.youtube.com/watch?v=3Ajqf_F6axQ

If I find the military exercise I will either edit this post or post it below. Some say even though it should miss Earth, it may come even closer to our moon (?).

Also, from NASA: http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2005%20YU55;orb=1;cov=0;log=0;cad=1#orb

1. Maybe that Apocalypse Dude was off by a few weeks?
Then again, nah.

4. They are saying that an Earth impact would leave a 5 mile wide crater 2000 ft deep.
Though the projection is that it will pass by us with no impact.

15. It's close relatively
1 Lunar Unit = 404,000 km
404,000 * .85 = 343,400 km

Sound travels at 340.29 m/s = .34029 km/s

If you were traveling at the speed of sound it would take 343,400km / .34029km/s = 1,009,139 seconds, or 16819 minutes, or 280 hours to reach it.

It'll be a cool thing in the sky more than anything else.


Apophis is the scary one IMO.

27. No. Apophis is classified as a "regionally devastating" asteroid.
If it hit Paris, the residents of London would get their windows blown out and might get some muddy rainfall, and we Americans would get some awesome sunsets, but that's about it. I wouldn't want to be in Reims though.

Remember, the asteroid that took out the dinosaurs was estimated to be about 10km wide, and even THAT didn't actually wipe out all the life on Earth. It just caused a multi-year winter that was a killer for the large-bodied dinosaurs. That impactor today would kill off billions of humans, but on a planet with 7 billion of us, the damage would be short-term.

As I recall, the only true ELE type asteroid that we know of, with any chance of hitting Earth, that is capable of actually wiping us out completely, is Eros. Even that isn't actually an Earth crosser, but is an unstable Mars crosser that is projected to convert into an Earth crosser at some point in the next few million years. If that happens, there's a substantial chance it could hit Earth...eventually. It might take several million additional years before it finally hits us. But, if it did hit...:nuke: At 35km across, it would make that dinosaur meteor look like a firecracker, and would unquestionably cause global catastrophic damage. Luckily, that's a concern for people who will live a long time from now.

26. That seems high
Though it does heavily depend on the composition of the asteroid, there's a general rule of thumb about crater sizes called The Rule of Ten. In short, crater sizes are usually about ten times the diameter of the impactor. As I said, this does vary a bit depending on the makeup of the impactor and the type of rock it hits, but it gives a nice average.

2005 YU55 is estimated to be about 400 meters wide. That gives us an average crater size of 4km, or 2.5 miles across. Even THAT assumes that the impactor would lose no diameter as it hit the atmosphere, which would be unheard of. It's more likely that the rock would lose a substantial part of its mass, and the crater would be even smaller.

We're probably talking about a 1.5 to 2 mile wide crater. That sounds bad, but you're talking about poking a 2 mile wide hole in a 7900 mile wide bullseye. If you're on the side of the planet facing the impact, the odds of you getting killed are unbelievably small. If you're on the OTHER side of the planet, the odds are effectively zero.

18. There is one in 2029 called Apophis
It will be close the first pass. If it threads the needle just right after that, it in 2036 it could hit us. The odds of it hitting us are long, but they are way better than the odds of a lottery ticket.

5. Ok - for the slower crew.....
Will this have any impact on us on terra firma or our traveling companion?

That YT looked really, really close.

8. They don't think it will impact
Edited on Tue Nov-01-11 11:15 PM by nadinbrzezinski
But they fear it might thread the needle, and next time around it will.

13. This is not big enough to be an extinction level event
It will ruin somebody's life if it hits a city...but it is far from large enough.

That said, we should be able to avoid this with current technology. Hollywood writes good yarns, but the Ruskies are actually on working on the engines to reditevpct. At those scales even a degree or two should be sufficient

20. It'll be an interesting time.
I'm sure you're right, lots of new tech out may have an opportunity to be of some use.

23. I'm guessing if it landed on your head, you'd be extinct. Not you personally, but you get the idea.

24. Of course
If this lands on a city the energy will be about Hiroshima.

There is another one that is believed to be an ELE, that be Apofis. This...probably Tonguska.

Yes local major disaster, but hardly an ELE. trust me we get the big one, I might say good night Gracie. Or just a personal nasty car crash.

won't even notice when firestorm and shock wave hits.

17. FCC Publishes Handbook for National EAS Test

19. "How will the national EAS test be conducted?" and why that date:
How will the national EAS test be conducted?

The national EAS test will be conducted jointly by the Department of Homeland Security (DHS) through its Federal Emergency Management Agency (FEMA), the Federal Communications Commission (FCC), and the National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service (NWS), the three federal agencies that have EAS management responsibilities. FEMA is the arm of the DHS primarily responsible for developing national alert and warning functions. The FCC is an independent agency that grants licenses to or otherwise oversees EAS Participants. FCC rules regulate the transmission of EAS alerts. The NWS is a key player in the dissemination of local warnings via the EAS. The great majority of EAS alerts are NWS weather-related alerts.

On November 9, at 2 PM EST, FEMA will transmit the EAS code for national level emergencies to Primary Entry Point (PEP) stations in the national level of the EAS. The PEP stations will then rebroadcast the alert to the general public in their broadcast vicinity, as well as to the next level of EAS Participants monitoring them. This should continue through all levels of the system, until the national alert has been distributed throughout the entire country.

Pursuant to the FCC’s rules, all EAS Participants must report back to the FCC on the results of this test, including whether, and from whom, they received the alert message and whether they rebroadcast it. FEMA and the FCC will study these results to determine if there are problems with the system and, if so, how best to remedy them. We anticipate that a national test will be conducted periodically to ensure that the EAS is, and remains, functional.

FEMA and the FCC have already twice tested the EAS national code on a more limited basis, in the state of Alaska. The lessons learned from the Alaska tests will inform how the agencies conduct the national test.

What will people hear and see during the test?

During the test, viewers will hear a message indicating that “This is a test.” Although the National EAS Test may resemble the periodic, monthly EAS tests that most Americans are already familiar with, there will be some differences in what viewers will see and hear, which is one reason for conducting a national EAS test. The audio message will be the same for all EAS Participants; however, due to limitations in the EAS, the video test message scroll may not be the same or indicate that “This is a test.” This is due to the use of a “live” national code – the same code that would be used in an actual emergency. In addition, the background image that appears on video screens during an alert may indicate that “This is a test,” but in some instances there might not be an image at all. FEMA and the FCC plan to conduct outreach to organizations representing people with hearing disabilities to prepare that community for the national EAS test. Outreach will include specific information tailored to the needs of those with hearing disabilities that will be readily available at online sites.

In addition, FEMA and the FCC will work with EAS Participants to explore whether there are solutions to address this limitation. The text at the bottom of the television screen may indicate that an “Emergency Alert Notification has been issued.” This notification is used to disseminate a national alert and in this case, the test.

How long will the test last?

We anticipate that the test will last approximately3 minutes. While state and local EAS messages are limited to 2 minutes, there is no time limit for national EAS alerts. To evaluate whether the system properly interprets the national message code in the national EAS test, the message duration must be longer than two minutes.

Why is the national test being conducted at this particular date and time?

While EAS tests may be disruptive, they are important to ensure that the EAS is functional and that EAS Participants are prepared to issue alerts, and it is our intent to minimize disruption and confusion to the extent possible. The November 9 date is near the end of hurricane season and before the severe winter weather season begins in earnest. The 2 PM EST broadcast time will minimize disruption during rush hours, while ensuring that the test occurs during working hours across the United States.
