Asteroid 2013 TX68 Could Be a Close Shave at Just 11.000 miles on March 5th

If the asteroid does eventually enter our atmosphere and break apart would the resulting blast wave generate an EMP below the area where the asteroid broke apart?

The nearest object, apart from satellites and a few rocks, to earth is the moon, which is about 240,000 miles away. Mars at its closest is about 35,000,000 miles and that is the next nearest thing.

For the record, Venus can come a lot closer to Earth than Mars can.

No , the danger would be the shock wave resulting from the compression of air caused by the meteorite entering the atmosphere as seen in Chelyabinsk , as far as I'm aware they don't cause EMP.

Also it coming from the sun side no way to double check it
now on the way back in

Yeah, well, orbital mechanics work pretty well.

The close approach data indicates that the minimal approach distance is 0.000207036775593362 au.

So, well, that's the minimum. The maximum is 0.115300971101647 au.

Is the glass half full or half empty. I guess it doesn't matter since the rock is going going to miss, either way.

Boy that was a fast answer but still like this one better

That a very big window still open to change

That a very big window still open to change

Yes. The window will indeed change.
It will get narrower, not wider. That's the way close approach numbers get. The actual number will be somewhere in between.

That your opinion (Not Proof)
That does not make it so but we will see
But if it does hit it will be most likely be in South-Atlantic Ocean
between south america and Africa just my guess
below the equator

just my guess

Ok.
I won't ask upon what you base your guess.

That doesn't help much.

What am I looking at?
What OrbEls were used?

or are you just fishing

Very little difference between JPL6 of Feb 11/16 to JPL7 on Feb 25/16

a reply to: Trillium

No.

As I pointed out, the orbital elements (as posted on the JPL site) provide the minimum and maximum close approach distances. None of which show the object passing through Earth.

But, from your image, I don't see the southern hemisphere as an impact point.

Ya the Facebook video give a better viewing angle of Asteroid - Meteor and the Earth relative distance
the picture is at a angle that look like it passing through Earth. That was cause by a wrong aliment of
Asteroid - Meteor and the Earth

Normally after 3 to 5 Reference change you get a idea which way it heading, closer or away from earth

Actually, with more observations what you normally get is a narrowing of the margin of error.
Normally, the window gets smaller, it does not shift.

Nope, not just his opinion. From your link:

CNEOS's new prediction for 2013 TX68 is that it will fly by roughly 3 million miles (5 million kilometers) from our planet. There is still a chance that it could pass closer, but certainly no closer than 15,000 miles (24,000 kilometers) above Earth's surface.

The estimates make it clear that it will not impact the Earth, and any uncertainty in the trajectory will indeed gradually place it closer and closer to the nominal (somewhere between the minimal and maximal distance).

from Reference JPL7 Inclination 1.109245744034967

difference of only .000000000052488 but still making the orbit going closer to earth

will see on next reference JPL 8 after it pass I guess

Inclination alone is insufficient to determine close approach distance. There are, after all, three dimensions to consider. Not to mention that inclination is an angular, not linear, parameter.

Can you provide the difference in minimum approach distance between 6 and 7?

a reply to: Phage

Not to mention that inclination is an angular, not linear, parameter.

Yes it is angular and as the angle get smaller in this case it does bring the orbit close to earth

As for the min. approach distance between 6 and 7 it is .000000000019224 Deg.
Celestria has it limit lol it more of a viewing program can only give distance to one object at a time
I'm still just learning LOL

a reply to: Trillium

That is an angular dimension, not a linear dimension. It has no meaning in regard to distance from Earth. Close approach distance is a linear parameter, not an angular parameter.

Please look up the definitions of the terms used.
