Another asteroid similar to Russian meteor zooming past us harmlessly

Another asteroid similar to Russian meteor zooming past us harmlessly

science.nbcnews.c om

A newly found asteroid will pass by Earth at about the distance of the moon's orbit, with its closest approach coming at 2:35 a.m. ET (7:35 a.m. UTC) Monday.
Named 2013 EC, the asteroid is roughly the size of the space rock that exploded over Russia two and a half weeks ago, measuring somewhere between 10 and 17 meters (33 to 55 feet) wide. The asteroid that sparked the Russian meteor is estimated to have been about 17 meters wide when it entered Earth’s atmosphere.

Well, just as the article states, we are not being visited with any more asteroids than we have before, they are just getting better at detecting them. This asteroid is about the same size as the one that landed in Russia a few weeks back. It has absolutely no chance of hitting the earth. You know, with us being able to detect these things like we can now, maybe in the next few years we can send crews to further study and possibly try and alter the projection or blow it up.

Missed it by......that much.

The Bugs are launching meteors at us. Where is Casper Van Deen?

If they weren't able to detect the asteroids before, how do they actually know that we are not being visited by more asteroids. You need two known figures to evaluate something like that properly. Has an asteroid like the one in Russia hit the earth in say the last thirty years? I think this info was created without proof at all.

The truth is that science really does not know for sure if there are more asteroids. The addition of technology cannot be used as proper evidence to evaluate this.

This data is unavailable to the scientific community, it is detected, followed... and controlled
by the military. They have the technology to track this, they dont share it.

"The satellites that monitor the skies around the world for missile launches also detect brilliant incoming meteoroids, including startling events much smaller than the Chelyabinsk bolide," said asteroid expert, Clark Chapman of the Southwest Research Institute in Boulder, Colorado.

This type of information is extremely valuable for helping scientists understand the potentially dangerous cosmic environment of planet Earth, Chapman told SPACE.com. [See video of the Russian meteor explosion]

"In the past, these data have been partly withheld from the scientific community. They should be released immediately, while scientists, emergency management officials, and others are trying to understand what has happened, where people might have been hurt, and where valuable meteorites might befound," Chapman emphasized.

Military higher-ups and the agencies involved are guarded about how potent their satellite sensors are as they stare at Earth for nuclear detonations, missile launches and the like.

In a new exclusive interview with SPACE.com, U.S. Air Force Brigadier General Robert Rego, who is in charge of the policy guidance behind the data release, said the Air Force Space Command is "circling the wagons" to close some loopholes in the dissemination of potentially sensitive information.

Just a coincidence. Or perhaps something disturbed the asteroid belt and some rocks got sent our way.

Yeah your gunna see a lot of this within this year. The alien invasion has begun.

Prophecy of the Rattlesnake
The Cherokee Calendar also speaks its voice telling that at this time of the fingers striking Jupiter that Orion Star System will awaken. And the Pleiades and Orion will war once again as in old. Jupiter and Venus will awaken to its destiny of TIME UNTIME of cycles. Orion will WAR with Pleadies, Jupiter will WAR with Venus. The time of the Cherokee UKU's will be at hand. In the year 2004 and 2012 an alignment will take place both on the Cherokee Calendar and in the heavens of the Rattlesnake Constellation both. It is the time of the doublehead serpent stick. It is the time of the Red of Orion and Jupiter against White Blue of Pleadies and Venus. It is the time of the Uku's choosing. It is the time of the Beloved Woman and MYSTERIES OF TIME UNTIME. It is the Time Untime of the THUNDERBOLT and the spirits of Lightning Mountains. In the year 2004 and 2012 the Cherokee Rattlesnake Constellation will take on a different configuration. The Snake itself will remain, however, upon the Rattlesnake shall be added upon its head feathers, its eyes will open and glow, wings spring forth as a winged Rattlesnake, it shall have hands and arms and in its hands shall be found a bowl. The bowl will hold blood. Upon its tail of 7 rattles shall be the glowing and movement of Pleiades. The Rattlesnake shall become a FEATHERED RATTLESNAKE or FEATHERED SERPENT of TIME UNTIME.

Not quite. The truth is, it's relatively easy to get an accurate historical record of asteroid impacts on the Earth. From that, we can extrapolate asteroid frequency.

How is that by the way? If no one sees it or it is not recorded by any technological device, are you suggesting that there is some way to find some kind of trace of the asteroid hours, days, weeks, or months after it has entered earth?

reply to post by WorShip


Yep. They're called craters.

reply to post by CLPrime


Smug reply, however you forgot to take into account REALITY. 70% of the earths surface is ocean. So your scientific data ignores potentially 70% of data?

Nice one.

reply to post by WorShip


All you need is 30% of the data. Probability indicates that the impact distribution should be the same over water as it is over land, since asteroids don't choose to impact more often per square kilometer in one or the other. The same principle applies to public surveys -- 30% of an evenly distributed set of data is more than enough to make conclusions about the entire set.

despite the doubtless very impressive neo detection systems in operation, the russian fireball was a reminder that we won't necessarily see every incoming rock with more than a couple of minutes advance warning.

reply to post by CLPrime


That would be logical to assume. but not necessarily correct. Asteroids could come in waves, many asteroids could come under the same event. If a large number of asteroids have come from a certain place and are more likely to hit earth at certain places, you might get a misrepresentation of data?

reply to post by WorShip


If they come more than a few hours apart, then they will still be evenly distributed, since the Earth will have rotated significantly in that time. And if they come less than a few hours apart, then they represent a single impact event.

The possibility is always there, of course, that the frequency of smaller asteroids could be increasing, especially those that airburst like the one over Russia, or ones smaller than that. But we do have the ability to say with humble certainty that actual impact events have not increased. And, as a testament to our ability to note increases in impact frequency, we have what's known as the Late Heavy Bombardment of about 4 billion years ago, which is apparent from lunar craters.

From that it sounds like they can only detect them as they enter the atmosphere.

Also, you would expect the frequency to increase at the poles since they move less - so have we potentially lost data there. For example, a 20 year period of daily asteroids that approach the earth from the north pole(maybe slightly unrealistic, but still), a significant amount of data would not be accounted for? Also, I'm not supporting that there are more asteroids, I was just questioning this ability to know the frequency of asteroids on earth irrespective of being around to measure it. This is in light of the fact that the earths crust is also changing often, so more data is lost there. However, since the moon has been around a similar length of time it would be reasonable to use the moon's data as evidence for asteroid frequency, despite it being quite a bit smaller then earth (another potential misinterpretation of data).

Also, is there not a theory that, based on observations of mass extinction events related to comet phenomena occurring every !26,000 years, that asteroid frequency increases in these periods due to movement of celestial bodies seen or unseen? I believe we are currently about 26,000 years since the last extinction event of this nature. Therefore, it could be entirely accurate that asteroid frequency has increased.

You may be right ArMap,

Whether they can detect them before enter I am not sure...

The system is in place to detect, locate, and report nuclear detonations in the Earth's atmosphere and near space, doing so in near real-time. It makes use of space-based sensors and ground-based mission processing systems. The sensor payloads are carried onboard the military's Global Positioning System navigation satellites, as well as Defense Support Program spacecraft.

Also, this...now they say the Russian asteroid was in Earths orbit for thousands of years,
and they did not know this? These "experts" I think have to make educated guess much.

Now that they've worked out the orbital path of the meteor that blew up over Russia last month, scientists are saying that the asteroid behind the blast crossed Earth's orbit regularly for thousands of years.cosmiclog.nbcnews.com...
