Could Earth be at Greater Risk from a Deadly Asteroid Impact Than We Realize?

Detected from aerial radar surveys, the huge impact feature comprised a circular depression visible in the subglacial bedrock, around which a clearly discernible elevated rim could be seen, along with other gradually deteriorating features that had lingered since the original impact occurred. Analysis of sediment collected from the location indicated the space object that left the feature was mostly composed of iron.

In 2018, the discovery of a massive asteroid impact feature in northwest Greenland came as a surprise to many planetary scientists and others studying impact events that have occurred in Earth’s long history.

Despite being an estimated 20 miles in length, it was also clear why this particular impact feature evaded detection for so long: it was concealed beneath more than 3000 feet of ice, which had slowly accumulated since the last ice age.

If the end of mankind is going to end this century, my bet is that it will come via an asteroid collision with Earth.

I think so. This is because of all the near misses I've heard about over the years. And these are just the ones they tell us about! If this is Earth's fate one day, I wonder if they (the government) will tell us about it before it happens?

If it ever does happen, I hope they don't tell us about it. Could you just imagine all the chaos that would happen if they did tell us. I would rather having the end of the world coming to me suddenly instead of over a long drowned-out out process.
