sharkman Posted March 5, 2012 Report Share Posted March 5, 2012 (edited) Remember those asteroid movies? Scientists are saying that in 11 months, an asteroid will come very close to the earth, and the gravitational pull could suck it into impact. It would have the explosive power of a nuclear weapon. Russian Scientists have released data indicating a large 60-meter asteroid (2012 DA14) is plummeting towards earth with an expected collision date by February 2013 stating, [sic]… time to build a spaceship to confront it, has run out. No need to panic, but a very interesting development. Edited March 5, 2012 by sharkman Quote Link to comment Share on other sites More sharing options...

DogOnPorch Posted March 5, 2012 Report Share Posted March 5, 2012 There is a doomsday asteroid scenario every year. Yup...last biggie was 1908...and it missed hitting civilization. There is cause for long range predictions, though. We do have some rather large neighbors. Quote Link to comment Share on other sites More sharing options...

This story seemed to have a pretty small presence for such an important situation. They're not going to panic the public, it'd be anarchy..I assume they first want to pin point where it will possibly explode if it does come to that ..this probably won't happen but they could evacuate the areas where they think it could hit .. but probably not Quote Link to comment Share on other sites More sharing options...
Wild Bill Posted March 6, 2012 Report Share Posted March 6, 2012 I read the link. There's a definite "National Inquirer" aura to that site! "Close" flybys happen all the time. A direct course of impact is relatively rare. Just because an asteroid's orbit brings it close is no reason to panic. What's more, observations allow close predicting of an orbit's path. The trajectory is not likely to suddenly change, other than a very small amount due to escaping gases if the asteroid feels some heat from the sun or whatever. However, if you want to sell newspapers, a headline saying a collision is not a lie! A lawyer's trick, maybe but not legally a lie! Quote Link to comment Share on other sites More sharing options...

This story is big enough that several nations are commenting on it and NASA is commenting on it yet there is no presence of it in the media. A media that runs all kind of nonsense not running this seems odd. As far as impact goes, the issue is what effect the earth's gravitational pull would have on its course.

Wild Bill Posted March 6, 2012 Report Share Posted March 6, 2012 As far as impact goes, the issue is what effect the earth's gravitational pull would have on its course. No, the earth's gravitational pull has been affecting the course for months if not years now! In weightless space, gravity becomes a significant force over vast distances. It doesn't just suddenly jump out and grab something when it gets close, like a spider and a fly! The earth's pull has long since affected the asteroid's orbit. Astronomers who take observations can clearly chart where that asteroid is going. If it were going to hit the earth we would see it NOW! If it's going to miss the earth we could see that as well. It's path is already long laid out. Quote Link to comment Share on other sites More sharing options...

In fact, gravitational forces are the vastly dominant factors when it comes to the motion of bodies in the solar system. The pulls of the Sun and the planets control their trajectories, with only very slight corrections due to radiation pressure, solar wind, etc. Computer models can very accurately calculate forward in time the positions of objects such as asteroids, provided that their current position and velocity is known.

Variations séculaires des orbites planétaires or VSOP is a typical calculation to get orbital elements. Quote Link to comment Share on other sites More sharing options...

Guest Manny Posted March 7, 2012 Report Share Posted March 7, 2012 In the past 2-3 years there have been several of these, asteroids that were going to make a very close pass near Earth and some of them were observed very far off. There is still considerable uncertainty about the trajectory of such asteroids because they don't know its precise velocity or mass, and they don't know its composition. So while it may appear to be heading straight for us, the exact trajectory will be revised a number of times as it gets closer in. Fact is these occurrences are probably quite common, happen all the time but it's only recently that we've even been looking. Since then we've seen several asteroids come close, some of them even passing between the Earth and Moon. Quote Link to comment Share on other sites More sharing options...

DogOnPorch Posted March 7, 2012 Report Share Posted March 7, 2012 This rock is bigger than the average neighborhood space rock. 60m doing 8+km a second can make quite the mess. So it should be watched carefully. It will be back in time if it doesn't hit... Quote Link to comment Share on other sites More sharing options...
