Good news! Nasa dramatically reduces the chances that 'city killer' asteroid will hit Earth

The astronomical community expects the probability to fall to zero.

THE CHANCE THAT an asteroid capable of wiping out a city will hit Earth in eight years has been cut in half to around 1.5%, according to new calculations from NASA.

The drop in odds had been widely anticipated by the global astronomical community, which now broadly expects the probability the asteroid will hit Earth on 22 December, 2032 to fall down to zero.

For more than 24 hours, the asteroid did have the highest probability of hitting Earth of such a big space rock in modern forecasting.

Updated calculations posted by NASA late Wednesday said the odds of a direct hit had fallen to 1.5% from 3.1%. 

This reduces the chances from one in 32 to one in 67

The European Space Agency’s separate calculations plunged further to 1.38%.

Richard Moissl, head of the ESA’s planetary defence office, told AFP this had been expected as the “uncertainty region” where the asteroid could strike starts to “slip off” Earth.

The percentage chance will likely still “wiggle slightly up and down a bit” but is now expected to soon fall below 1%, he added.

It is not clear whether that will happen before the James Webb Space Telescope turns its powerful gaze to the asteroid next month.

There is still an 0.8% chance that the asteroid will hit the Moon, according to NASA.

The asteroid, which is known as 2024 YR4, was first detected in December.

It is estimated to be around 40-90 metres wide, which would not cause a global catastrophe, but would still be capable of causing significant destruction to a city.

The last time an asteroid of greater than 30 metres in size posed such a significant risk was Apophis in 2004, when it briefly had a 2.7% chance of striking Earth in 2029 — a possibility later ruled out by additional observations.

    No tv, no wifi, no mobile devices – for a start. Everybody eats the same meal, nobody leaves the table until we’re finished. If we’re finished early then we talk to one another. Even if we all don’t make it to the table at the same time (if someone is working) then everybody else still eats together. It is that simple.

    My 6 and 3 year olds usually compete with each other when setting the plates and cutlery…I hope they continue to do so into their teen years.

    We always share 1 childhood experience (good or bad) of our own with kids at dinner time and wait for everyone to finish before getting up.

    I tell them to sit down, shut up, and eat this crap. If they are hungry enough, following physical activity, there is no problem whatever. Articles like this annoy me.

    Once a week is enough for us for sit down family meal. The kids are generally hungry straight after school. The husband can finish work any time between 5 and 7.

    Everyone in the house has their own tastes so sometimes I cook 3 different meals at the same time. My husband can’t eat red meat or anything with cream, my one son doesn’t like things spicy (like me), my one son also turned vegetarian for a while (that phase is over), my one son and daughter are the only people in the family who like fish and prawns.

    So meal times are organised chaos.

    As a picky eater as a child I didn’t agree with forcing a child to eat a food they don’t like. I am very happy to feed them what I know they will eat be it a stir fry, roast, curry, pasta and so on.

    I grew up in a ‘eat when you are hungry’ house. No set in stone mealtimes. It was more of a relaxed environment that way. Dad often worked till late at night on a car engine (he wouldn’t leave it till it was fixed) and would have his dinner reheated in the microwave.

    I have been to extended family sit down meals and they are awkward. Expectations for kids to clean their plates, bribery with desserts, no elbows on table, kids getting bored, parents getting irritated. More hassle than its worth sometimes. ..

    Hunger is a great sauce. There weren’t too many picky eaters when food was scarce. I understand some people have aversions to certain foods but with kids sometimes give them an inch and they’ll take a mile. They eat what’s for the dinner in our house and if they don’t like certain things in it e.g. Mushrooms, they can pick them out. A little bit of everything.
