4Ld is close for a civilisation ender would not wipe ALL humans out but would wipe out a good 7 to 8 billion with little trouble over a year as everyone died of starvation would be very violent & terrible as humans wiped themselves out in a war for food & water
several scientists have said publicly that roughly speaking a 1 kilometer wide asteroid at average speed would create global nuclear winter which in turn would wipe out billions in food shortages and weather conditions. depending on where it landed it would have different effects landing on land it would send out massive amounts of flaming rock over many kilometers where it would start massive wild fires on sea it would create significant tsunamis which would simply wipe many citys off the map, including the fact most human civilization concentrates around waters edge. what has occurred to me is the random chance of a 1LD object which strikes the moon could bounce pieces off at earth that would be difficult to track i expect none of the majority of wold leaders would release the information & they would run for their bunkers & watch it unfold on TV. when in reality do-able right now is a global joint missile & satellite defense system combining china usa russia & private contractors to have a multi pronged defensive layering system on alert. however the people who make all those decisions think they will be safe in their bunkers so they dont care about anyone else. they have no personal imperative to create the response to protect other peoples lives like they would their own.
This is how far away the asteroid is approx. to-scale with Earth and Moon. One pixel is approx. 1000 miles. (I've line-wrapped it but its really one long line.) o--------- --------- --------- --------- .

What is this distance unit "Ld"? It can't be light-day, since that distance encompasses the entire solar system, including the Kuiper Belt.
My question about 2 Kilometres being a close call was in regard to how much Earth gravity would have on the asteroid at such distance? That is ignoring all the permutations inherent within the rest of the planets in the solar system Would any effect (can it be calculated) result in the asteroid having a nearer of further flyby in the future? How far in the future? Please Register or Log in to view the hidden image!
That's only about 5 times as far away as the Moon. Peanuts to space. Is has an effect at all distances, but the force decreases as the inverse square of the distance (as per Newton's law of gravity). It can be calculated. No doubt whichever organisation(s) are in charge of tracking near-Earth have calculated it. The effect could be either: nearer or further next time around. It depends on the details of the orbit.
I know that. But at its current distance will Earth gravity move it 2 cm or 2 km? Please Register or Log in to view the hidden image!
It's more a matter of by what angle the orbit is diverted from the path it would have followed if the Earth hadn't been nearby. Orbital perturbations can be very small, but still add up to huge effects going into the future. A tiny push now might mean the difference between a near-miss and a collision with Earth a few hundred years down the track.
And note (Michael) that there's no reason to assume that the subsequent flyby is closer or a bigger danger, as opposed to a farther, smaller danger. The possible future paths that are less hazardous far exceed the possible future paths that are more hazardous.
i checked & jpl neo list it as 5.1 LD keeping in mind they simply cant see some things coming & you see them suddenly appear only a day or so out a lot closer

I think that humans deserve to be wiped out by something eventually. Also the sooner it happens the better. Because lets face it: Humans are a shitty species and we love to make life miserable for one another and we are also extremely greedy and many humans also take great joy in seeing another human suffer hardships and misery in life so we deserve what's coming to us eventually. Humans have lost their innocence a long time ago so we deserve to be wiped out eventually.
