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)

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).

LOL where did I say it was going to impact. I said if it was going to impact I said my guess was so and so place a GUESS
And that what make this very interesting the last observation was on 2013-10-09 and none will be had until it pass the earth and get on the viewing side, can't look at it in the day time LOL
So after it pass like you say they can refine the orbit closer to it nominal trajectory.

(Insert Bionic Man sound)

Suuuch a rad sound.

As said has a very small number of observations making it very difficult to plot its orbit and size.

Guesstimates range from .02 AU (4.5 mil km) to .0002 AU (30,000 km) to as much at .01 AU (15 mil km)

Size ranges from 21m (about size of Chelyabinsk object) to 52 m (about size of object that carved out Barringer Crater in Arizona)

NASA has declared has Nil chance of impact

As gets closer telescopes should be able to track it and refine orbit

Like the old saying "Its the one you dont see that gets you..."

That the problem they can not right now because it coming in
from the sun side
See here
They will not see it until it pass again

Interesting read and input on the subject, does anyone have information or a theory as to why NASA changed their minds about it's distance and threat level? I read they deleted the entry .

Also not a chance off a radar image of it also
because it has a poorly known orbit. Radar observations require very precise pointing.

No Radar Image

Now
The Earth's mean radius is determined as the average distance from the physical center to the surface, based on a large number of samples. This is roughly 6,371 kilometers (km) or 3,960 statute miles.

11,000 - 3,960 = 7,040 Miles

So the Asteroid could be as little as 7,040 miles to earth mean surface WOW

Just hope it does not take-out any satellite on it way in and way out

Yes. That would be extremely unlucky. But Lloyd's would cover it.

It would leave a lot more junk up there though.

Here some update for 2013 TX68
not much has change so far

From EarthSky

My guess is they have something up their that can see it but
They can not say so because it would let other know they have

Apparently it just passed us??!!

UPDATE MARCH 7, 2016. Asteroid 2013 TX68 safely passed by Earth on Monday morning. According to the Minor Planet Center, the space rock’s closest approach occurred on March 7 at 13:42 UTC (8:42 ET) at a distance of 2,542,960 miles (4,092,497 km) from Earth, just a bit closer than the nominal 3 million miles previously estimated. The space rock approached our planet a few hours earlier than expected. The previous estimate indicated asteroid 2013 TX68 was due to pass by Earth around March 7 at 7:06 pm ET (March 8 at 00:06 UTC).

yes, thanks for the good eye there....I was searching for tomorrow....a reply to: Spodeeodee

Yes. With all the drama and sensationalisation that is so common on forums or in the media, in reality no one would know the difference unless they were tracking the asteroid with a telescope.

Now, the asteroid Apophis is the one to watch out for. It's so big and will pass so close to us that you'll be able to see it with the naked eye.

well look like 2016 DY30 only miss us by 5,000 miles

2016 DY30
