Summary

A 27-inch asteroid, C0WEPC5, entered Earth’s atmosphere over Siberia on Tuesday, creating a harmless but visible fireball.

This marked Earth’s fourth detected asteroid strike of the year and only the 11th “imminent impactor” ever recorded.

The asteroid was detected by the Kitt Peak National Observatory ahead of impact, showcasing advancements in asteroid detection.

Separately, a larger asteroid, 2020 XR, measuring 1,200 feet in diameter, will safely pass Earth on Wednesday at a distance of 1.37 million miles.

      I don’t understand why imperialists decided to use one apostrophe to indicate the larger unit and two to indicate the smaller unit. It makes no bloody sense.

        Uh I’d just like to point out that a meter is m and a milimeter, which is shorter, is mm. So y’all apparently don’t make any bloody sense in metric either.

            mm = meter meter so 2 meters amirite?

            Making fun of the imperial system is an old game and so easy to play that I’ve never seen anyone actually lose at it, until now. LOL

      The impacts are not comparable but perhaps in terms of detection methods they are handled mostly the same. On the one hand, being able to detect a 27 inch asteroid doesn’t matter much but on the other hand, if you can detect something that small, maybe you can detect anything that does matter. Unfortunately, I don’t think asteroid size is the only factor in detectability. A lot of it has to do with which direction it is coming from and if that is functionally obscured by the Sun or other objects.

      The point is, if they could detect a 27” asteroid, something bigger won’t be an issue [for detection].

    I’d love to know what percentage of the Earth’s population would be totally fine with an asteroid taking us all out. I’d be willing to bet it’s higher that it’s ever been.

      I’d rather we get eradicated but the rest of nature is fine.

        There is a deep sea and creatures living deeply underground. Chance is even if an even wiped out everything on the surface of the earth after some few million years the surface is populated again.

      On some sardonic humor level, sure. But I don’t think many people are actually ready to die tomorrow, and no one is ready for an impactor that does something in between like plunge us into 200 years of suffering because we can’t grow 70% of the crops we need.

        AFAIK meteors come with a velocity spread of about a digit, which translates to a couple digits of energy, and then back to a single digit of blast radius. In Siberia that’s a nothingburger all around.

        Also, the headline did say “massive”.

      It’s amusing, but not very helpful. Granted, what could the average reader do with an exact size, besides adjust their level of panic?

      On second thought, the first one is very easy to picture 😺😸

    What is an inch, what is a mile, what is a feet?

    Is this even about space?

    Who’s aiming these things? If you’re gonna keep throwing them at Russia, then at least put a crater where Putin’s hiding.

    Aliens were supposed to invade today but I guess there wasn’t enough melee in South Korea, so I guess I’ll settle for a colossal asteroid impact instead.

      Terry Pratchett apparently had a sword made from a meteorite.

      Alec Steele made a video about trying to work meteorite metal.

    Wife saw two shooting stars in short succession a few days ago. I wonder if it was little grains preceding this guy or just random junk.
