Apothis is coming to visit

Bruce Willis is needed to fix a leak on an oil well.

Let him go out with a bang!

Can't really predict where it will hit, just where it can't, so somewhere in the Arctic circle should provide a good box office seat.

I'd rather die than live in the snow.

They really don't do very good about forecasts of climatological impacts.
I happen to think Earth was totally overcast in the Age of the Dinosaurs and that weather was moderate including the Poles. But surface pressure was greater, which explains the demise of really big animals. The whole niche has disappeared. The accademics never mention that.

Tour wish may be granted.

Actually there are no prior qualified predictions, so we can't say they aren't any good at them. None of the asteroids tracked by astronomers included predictions of an actual impact. Always their predictions were of near misses, which is what we got. Predictio ns of actual impacts came from such sources as the Enquirer or Global News or similar media whose sales or viewings were based on not true stories.

I am not sure what you mean by surface pressure. Do you mean over population? Well, if that is what you meant, it would be like a colony of rabbits that over populates. Some (man) die off, but a few, enough to restart the colony always remain. They are fewer so they find food the dead ones can't eat. And lo, the colony grows again. So over population is not what killed them. A 500 degree day was probably more of a killer, especially if accompanied or followed by 2 or 4 years of no sun light for plants to grow with.

Regarding the small size of what survives, got to give it to Darwin and evolutionary pressure. Also how would you want those critters bigger than an elephant to move? Back in the Dino days the Earth's Oxygen content was higher which gave their cells more energy potential. Also the earth was smaller (it adds 1/8 inch every year to it'[s size) so the gravity was less which made it easier to move. Darwin again, stuff too heavy to move and always short of breath could not compete with lighter critters that could quickly move and not have breathing issues.

There are scheduled meteor showers every year. I have watched several of them. They are really cool to watch from a ship way out in the ocean. I once experienced a big one hitting the ocean near us close enough to see the splash and the hiss. About a mile away I think. Asteroids are different than meteors, Although if an asteroid got mixed in with a meteor swarm.it would be hard to tell them apart. Most asteroids aren't that big, baseball sized mostly and would disintegrate just like a meteor usually does as soon as it hit the atmosphere. It is the ones the sie of a house or a whole city we worry about.

I have no reason to believe once in Jupiter's gravity well much escapes it.

Jupiter and Saturn are our bodyguards. Both have in the past century taken hits for us that would have destroyed us. The Shoemaker Levy 9 comet collision hit Jupiter with the force of 300 million atomic bombs. It took weeks for that impact mark to vanish. Our true danger time is when both Saturn and Jupiter are not in position to attract inbound objects. That is like a goal keeper walking away from the net to go grab a soda. Stuff can happen then. Of course stuff inside jupiter's orbit, such as asteroids, or traveling inward from North or South of the sun can still find us. We have very few observatories that point in those polar directions. A big advance was the aunch of space borne satellite radars, but they too have some coverage limitations.

Asteroid path prediction is a fairly inexact science. The further back in time of the first prediction the more likely the predicted path will need revision. Any impact with other space debris must and will affect the path. A small impact has a small effect, but the further away the impact was, the greater the orbit change an AU or 3 later away will be. Right now today a deflection of only 0.000032 degrees would put the impact dead center on the equator or knock it up high enough to be no threat at all. Of course the longer we wait the bigger the angle of deflection change has to be in order for the asteroid to be no threat at all. A;though this one is the size of the Rose Bowl Stadium, it is not hollow. It has enormous mass. If you wait 2 or 5 years before doing anything, you could put a dozen Saturn V booster engines on it and not cause enough deflection in it's orbit to do a durn thing.

Sadly the Earth lacks an Asteroid Defense Agency. We also lack enough technology to do a durn thing about an incoming threat even if we saw it coming from 40 years out. We would be like wasps trying to stop an oncoming 18 wheeler from hitting their nest by ramming the windshield. splat splat splat and then crunch.
