PureGenius Posted August 31, 2013 Share Posted August 31, 2013 (edited) MAJOR FIREBALL EVENT: Two nights ago, a ~100 lb meteoroid traveling 53,000 mph hit the atmosphere over the southeastern USA and exploded, producing sonic booms and a fireball as bright as a full Moon. Researchers are now scouring the countryside for fragments that could reveal the nature and origin of the meteoroid. A movie, more information, and updates are available on http://spaceweather.com. I postulate that this object was only moving at 1,000 miles per hour . This leads to the conclusion these meteors are almost at rest from an astronomical standpoint. These are resting between the galactic arms of our galaxy . I think Slow interstellar meteors would be a sufficient name, for these object's. The solar system we are in is spinning around our galactic center on a galactic arm at 52,000 miles per hour . This also explains why it's so difficult for astronomers to spot these slow moving objects.

EdEarl Posted August 31, 2013 Share Posted August 31, 2013 The article said 56,000 mph. I don't know how you figure 1000 mph, but it appeared to me the meteor traveled about 1/4 the circumference of the visible Earth in a second or so. The Earth's circumference is about 24,000 miles, only 1/2 is visible in the video, so that's 12,000 miles--at the surface of the Earth. IDK how high the meteor was when it appeared on the video, but it had to travel much more than 1000 miles in a fraction of a minute, which is much faster than 1000 mph.

ajb Posted August 31, 2013 Share Posted August 31, 2013 (edited) I postulate that this object was only moving at 1,000 miles per hour. Based on what? As an aside; I once saw a fire ball, it was impressive but not as good as the one you mention. Edited August 31, 2013 by ajb Link to comment Share on other sites More sharing options...
PureGenius Posted August 31, 2013 Author Share Posted August 31, 2013 (edited) The fact that these meteorites keep escaping detection, and that they are most likely lingering remnants of planetary impacts left behind, if they are outside all gravitational influence ie not accelerated then it stands to reason , these object's are lingering between thegravitational potential of our galactic arms. I'm saying these meteors are moving at 1000 mph and that our galactic arm ie our solar system is what ran into the object at 52,000 miles an hour . So velocity a 1000 +velocity b = 52000 = 53,000 miles per hour impact. And yeah I've seen big ones but nothing this big .

ajb Posted August 31, 2013 Share Posted August 31, 2013 (edited) The fact that these meteorites keep escaping detection... Meteors are due to meteoroids (small bits of rock) that are from the size of a dust speck to that of a grain of rice, these hit the Earth's atmosphere all the time. Larger objects do hit the atmosphere, but these are much rarer. Meteoroids can be up to a meter across. Fire balls are just meteors that are brighter than usual; the objects in question are still small objects. This is why they are not detected until they hit the atmosphere. Larger meteoroids can survive and hit the ground; then they become meteorites. But again these are relatively small objects. Only a few are recovered each year and made known to science. I know that space junk is tracked all the time. The objects tracked are of the order of cms. Edited August 31, 2013 by ajb Link to comment Share on other sites More sharing options...
Delta1212 Posted August 31, 2013 Share Posted August 31, 2013 He's saying that the meteoroid is traveling at 1,000 mph, while we're traveling at 52,000 mph. Thus it appears to move at 53,000 mph. Which ignores that it's still traveling at 53,000 mph relative to Earth and that there's no "astronomical perspective" for it to have a speed of 1,000 mph unless you arbitrarily choose a frame in which it's moving 1,000 mph. But that doesn't really mean anything. Link to comment Share on other sites More sharing options...
Janus Posted August 31, 2013 Share Posted August 31, 2013 The fact that these meteorites keep escaping detection, and that they are most likely lingering remnants of planetary impacts left behind, if they are outside all gravitational influence ie not accelerated then it stands to reason , these object's are lingering between thegravitational potential of our galactic arms. I'm saying these meteors are moving at 1000 mph and that our galactic arm ie our solar system is what ran into the object at 52,000 miles an hour . So velocity a 1000 +velocity b = 52000 = 53,000 miles per hour impact. 56,000mph is ~25 km/s. The Earth's orbital velocity alone is ~30 km/s The solar system's orbital velocity around the galaxy is ~230 km/sec. Any object falling into the solar system and starting at rest with respect to it, would be moving at ~42 km/s upon reaching Earth orbit. If the Solar system were to "run into" an object traveling at 1000 km/sec, it would be moving at ~233 km/sec upon reaching earth orbit. Even if it "came up from behind" the Earth, it would hit the atmosphere at ~233-30 = 203 km/s or 456,750 mph. So for an object to strike the Earth at 56,000 mph, and come from outside of the Solar system, its relative velocity with respect to the Solar system would have to be less than the solar system's orbital speed, and thus the object could not be "at rest" with respect to the galaxy. A 25 km/s impact speed is well within the range of an object orginating in the Solar system. To determine whether this is the case or not, one would need to know the trajectory of the object, and how it intersected with Earth's orbit. That and its impact speed gives its orbit. According to the article, this has been done and it has has been determined that the original orbit was contained within the Solar system. IOW, the impact speed and angle is not compatible with an object originating outside of the Solar system, and thus your hypothesis is DOA. 1 Link to comment Share on other sites More sharing options...

It's not a new type of meteor. The article clearly states that, based on the orbital parameters, the meteoroid might be from the main asteroid belt. An initial calculation of the fireball's orbit suggested it might be a fragment from a Jupiter family comet. Improved estimates of the orbital parameters point to a different kind of object: a main belt asteroid. If meteorites are recovered from the Tennessee countryside, their chemical composition will tell researchers more about the origin of the fireball. The main asteroid belt is part of our solar system, and the objects it contains are not, as you have suggested, entering our solar system as we orbit the galactic center. The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. The asteroid belt is also termed the main asteroid belt or main belt to distinguish its members from other asteroids in the Solar System such as near-Earth asteroids and trojan asteroids.

PureGenius Posted August 31, 2013 Author Share Posted August 31, 2013 Thanks for all the info, but I maintain its possible and probable that these meteors are between galactic arms. You guys are awesome smart such deductive reasoning. -2 Link to comment Share on other sites More sharing options...
Janus Posted August 31, 2013 Share Posted August 31, 2013 Thanks for all the info, but I maintain its possible and probable that these meteors are between galactic arms. No, it isn't. You can't just rewrite the laws of orbital mechanics to suit your own whims. Link to comment Share on other sites More sharing options...
Airbrush Posted September 2, 2013 Share Posted September 2, 2013 (edited) Thanks for all the info, but I maintain its possible and probable that these meteors are between galactic arms. You guys are awesome smart such deductive reasoning. EVERYTHING in our neighborhood of the galaxy is moving at about the same speed. How did you get the idea that meteors can "lurk between spiral arms" orbiting the center of our galaxy at only 1,000 mph? PG: "...The fact that these meteorites keep escaping detection..." The fact you don't know the meaning of "meteorite" makes me think you are guessing. Edited September 2, 2013 by Airbrush Link to comment Share on other sites More sharing options...
