2nd guy to be a Torino Scale 1, in the last few weeks. It may go away too, but
2009 is a lot closer than 2014!
2.8 km in diameter!
Still enought time to build a manned asteroid expedition.

No practical difference. Both are probably 'too soon' for anything but passive defensive
measures (e.g. building shelters and preparing for emergency evacuation of coastal areas).

2.8 km in diameter!
Still enough time to build a manned asteroid expedition.

I wouldn't place any bets on a successful mission in that time frame.

By the by , the Impact Table has changed since yesterday, two more
Torino Scale entries for this bugger, total of 3 1's now. The 2034
approach is set at 4.5 earth radii, and the sigma impact is only .21.
Still impact probabilities are small.

Remember, today's potential impactor is tomorrow's potential space
platform... Rocks in the tens of metres with low relative velocities
would be rather handy if `nudged'( -- much expense and technology
hides here) into HEO. Km scale objects, though, I don't think we'll
be in any shape to manipulate for quite a while, beyond heroic
efforts to nudge them at great orbital remove to kindly agree to
abondon their intention to intersect with us in the near future.

I wonder if we'd ever see on that page "impact probability = 1" for anything
significant.

Given that 'they' would have maybe a couple of months to plan stuff before
the big announcement if the probability just climbed to 10^-5 and then dropped
to zero.

Yeah, should always give JPL a week , or so, or more observations,
before taking the table to heart. I think the British guy's got gun
shy on QO104 after some 'chicken little' calls.
Still it amazes me that there are 2 km potential Earth impactors
wafting about, and one that might have our name on it.

One /does/ have our name on it. ... (pick one from following)

- But our telescopes aren't good enough to read the writing at that distance.

- But by that time all our names are already going to be written on tombstones.

:^) True enough,... ,

I'd guess it was around in WW I.
That was the one the British played some part in. ;-)

The solutions at 2034 is still there, at less than 2 Earth Radii.
Will probably change again.

But 2 of the Torino 1's have dropped off the risk list. This guy such has a lot
of passes inside the Moon's orbit.

Man, this guy has a lot of possible passes inside *GEO*...

Am I reading this right that deltaV as it goes by is around 9 km/s?
