A small asteroid may just have hit Earth today

skyblueworld

Some close ones on the way too.

Did you notice the speed of that little sucker? 38 km/s??? When you look at the orbit calculations that little 1.7 m - 3.8 metre wide object must have been sailing. How does an object this size attain that velocity?

Isn't that more like comet speed?

Dont have to get all stuffy.

Not being doom pornish.

I was only asked as we were meant to have got a light show from passing through the debris left by its tail (before it broke up), so wonding if that was the case, pretty logical queastion if you ask me? Not everyone keeps tracks on every rocks trajectorey hense why i asked.

I only asked as we were meant to have been traverliing through its debri trail if it hadnt of broken up.

Earth will be passing nearer to ISON's inbound path (i.e., before it broke up) than the comet's outbound path.

ISON's outbound path is much higher above the solar system's ecliptic, and Earth's orbit will not take it near that outbound path.

The Earth is not actually passing directly through the inbound path debris field, either -- just relatively close to it. However, I suppose there could be a meteor shower that could be associated with that debris field (again, that would be the debris left before it broke up).

Amazing what happens as the result of a key being stuck. I was simply answering your question and the "O" key in "No" stuck as a capital letter.

If I was shouting I'd have used an "!" exclamation point.

Chill.

So strange, I had a dream this morning about something similar happening. I was at a party and looked up to see a shooting star. But this was different, the "flash" or "light" of the shooting star ended but i could still see a rock falling. It then broke into 3 fireballs that scattered into different directions. One of the fireballs then broke into 3 again and also scattered, even reversing its direction. I was trying to get people to look up, nobody else saw anything. And then i was woken up.

No, what I am saying is that everyone laughed at the Russian prediction

There was no Russian prediction, the video in that thread is bogus (as the many replies to that thread should've shown you). Impact predictions don't come from the military or some obscure "Russian source" which can nowhere be found, they come from the astronomers.

Oh just to be clear, I'm not trying to predict anything. Just had a dream, seemed like it could be similar to this report.

Yeah, from your chart, people should be watching the sky's tonight/tomorrow as well, since that one is a bit bigger.

I would if we weren't being pummeled by snow until sometime in the late morning here in Pennsylvania. Measured anywhere from 3" to 6" outside so far, I'd much rather be seeing a meteor light up that night sky!!

Dreams are just what you are thinking about while sleeping. I had a dream once an asteroid hit and the pressure wave was coming and I looked around to hide, and I realized it was pointless so I turned around and watched it until I woke up. It was a rush! lol Earlier that night I was looking at doom porn about Dec 21, 2012, so that was probably why.

Wonder if it fragments from Ison debris? Any Astromoners can confrim or deny this?

Be intresting to see if there are a few more little instances over the next couple of months. Hopeffully if so they will be contained to uninhabited areas.

ISON at its closest was 40 million miles from Earth; that is nowhere near Earth. In fact, Venus is closer to Earth right now (about 30 Million miles) than ISON ever was.

Even after ISON broke up, its momentum would have kept all of the debris close to ISON, moving along the same general orbit as the intact ISON originally was moving (i.e., nowhere near earth).

That makes no sense. If the object fragmented, the particles would continue to spread. What force is going to stop the particles from moving away from each other? Each particle would now have its own elliptical orbit around the Sun like ISON did. Some particles would have now have shorter orbits and return toward the Sun earlier. Others would have longer orbits. It's possible that some may even escape the solar system all together. The fragments started spreading out shortly after perihelion. The question is: How fast were these fragments moving away from each other? Since the path of ISON is elliptical over the plane of the solar system, the distance the original comet would have traveled at its closest approach to Earth is more than 93 million miles (Earth-Sun distance). That's a long path. There could be a large separation distance of fragments over time. It is not possible to know if any of the fragments will strike Earth because nobody knows (I am assuming) how fast the fragment spread was. There are fragments, dust and gas. Matter doesn't just disappear.

I mean the comet's original momentum is keeping the pieces moving along the original general path now.

Obviously, the remnants can spread outward in a "cone shape" as they move along, but the original direction of its orbit was so far from the direction of Earth that even the diameter of the "debris cone" would be too small to have reached us as it passed Earth's orbit.

For example, the birdshot BBs fired from a shotgun could continue spreading out in a cone pattern as they got the farther away from the muzzle of the gun. However, if you were standing enough to the side of the shotgun -- even if you were generally in front of the gun -- the spreading cone of birdshot BBs would not hit you.

Ok my mistake.

I was just wary asking a ISON queation in case people put me in the woo woo crazy doom porn catogary when I was just asking a valid queation on its debries field we were meant to be passing through. And yes the awnser I have received are good its obvioulsy not from ISON.

Yup. Everyone seems to be confirming it now. We definitely had an extraterrestrial visitor

earthsky.org... _medium=email&utm_term=0_c643945d79-bf882b5142-393590781

Unfortunately, they think it broke up over the Atlantic, so we probably won't even get any debris from it so that we can study our new arrival

That's like comet speed when it's really far out. Apparently (i forget the source so I can't post it), some reports were saying that if a comet survives perihelion, sometimes they can reach speeds close to 1,000,000km/hr. so like... nearly ten times what that little guy was doing.

I guess though, accounting for the difference in size, it's probably equivalent, if not faster, than what we expect comets to do!

It would be moving its fastest along its orbit at the point it is closest to the Sun. Now that it is moving away from the Sun again, it would be slowing down as the Sun's gravity tries to pull it back.

That's kinda what I was thinking when I responded.
It is, however, pretty amazing that something so small can move so preposterously fast!

Well, regardless, I still find it ironic that there is chatter and then there is an event....that is the point I was trying to make.

Did you know: That for the cost of just ten 30 second Super Bowl commercials, we could operate a space based telescope which would do nothing other than discover and track objects like this and larger well before they hit the Earth?

Considering all it would take is about half the time of watching those commercials for a larger object hitting our planet to wipe out a good part of humanity you'd think we'd be doing it already right?

Priorities.

The asteroid's story at JPL: neo.jpl.nasa.gov...
It is an interesting insight into astronomy in action, how after the initial data was submitted to MPC, three sides (someone at MPC, someone at JPL, and a member of the public) calculated the impact independently and anounced it. Kinda flies in the face of the allegation that only space agencies can know of impending impacts and that they would keep it quiet to prevent mass panic.

Yes, sooner or later one of these things may fall in a major city and we can`t do anything about it

I wonder... do you consider any city in Africa as a major city? It may have fallen over one....
