Astronomers Discover 196-Foot Asteroid With 1-In-83 Chance of Hitting Earth In 2032 73
Astronomers have discovered a newly identified asteroid that has a 1-in-83 chance of striking Earth on December 22, 2032, though the most likely scenario is a close miss. Designated as 2024 YR4, the asteroid measures in at 196 feet wide and is currently 27 million miles away. Space.com reports: The near-Earth object (NEO) discovered in 2024, which is around half as wide as a football field is long, will make a very close approach to Earth on Dec. 22, 2032. It's estimated to come within around 66,000 miles (106,200 kilometers) of Earth on that day, according to NASA's Center of NEO Studies (CNEOS). However, when orbital uncertainties are considered, that close approach could turn out to be a direct hit on our planet.
Such an impact could cause an explosion in the atmosphere, called an "airburst," or could cause an impact crater when it slams into the ground. This is enough to see asteroid 2024 YR4 leap to the top of the European Space Agency's NEO impact Risk List and NASA's Sentry Risk Table. "People should absolutely not worry about this yet," said Catalina Sky Survey engineer and asteroid hunter David Rankin. "Impact probability is still very low, and the most likely outcome will be a close approaching rock that misses us."
As for where it could hit Earth, Rankin said that the "risk corridor" for impact runs from South America across the Atlantic to sub-Saharan Africa.

If there's still a lot of uncertainty around whether it will impact the earth at all, how can astronomers predict where on earth it is likely to strike? My simplistic assumption would be that if the error bars on our observations are big enough that we don't know if it'll hit, those same error bars would also mean that we aren't able to predict so precisely where that impact would be.

They know its trajectory and that its currently moving away from earth. They know when it will orbit back around. Based on this info they know what part of earth will be facing the angle of incident. What they dont have nailed down is a degree or two of trajectory which could amount to hundreds of thousands of miles. Still a near miss in the grand scope. However they have a good approximation of where the earth is facing and the axial tilt angled toward the asteroid. This gives them a slice of area to indicate a range of possible impact. When the time comes I bet these areas are going to be no fly and no ship zones. We might see transport halted for 48 hours.

The hit chance will have been log calculated by then, as well as the exact hit point, give or take a couple hundred kilometers, to account for minute gravitational trajectory shifts.

the real problem is going to be water strike vs a crater. A crater strike that big could create a local cooling effect from all the dust attenuating the sun. Maybe a regional micro ice-age that lats for a few years. A water strike will probably create a tsunami that is farther reaching and destruction more geographically spread out. You dont want to be a container ship in the wake of that mess for sure. I want to say a land strike would be favorable, but I am just not sure TBH.

By the time it will reach earth and either hit or miss, we still know which side of earth is facing to it.
Re: (Score:2)
Because we can simulate the rotation of the earth over time and project the ballistic path of the rock? There's some margin of error in the simulation, which is why they can only narrow it down to that "risk corridor" because they don't even know if we're really in the ballistic path yet.

Trump signed an executive order declaring the asteroid can only hit the southern hemisphere.
Re: (Score:2)
There is a mean projected path that has a projected impact location. There is uncertainty around that mean path. This follows from the basic statistics of an observation that includes noise.

The small planetary moon size are easy to track, but just because we spot some small ones does not mean we couldn’t be caught off guard. We get plenty that are discovered only days or weeks out, and pretty much for sure have missed ones coming close within a handful of earth diameter like this. Plus 60m if it’s solid rock and gets a steep enough impact looks like a 10 megaton explosion, with a shotgun breakup and craters totaling about 100m across. It would be small as far as impacts could be
