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.

This article is mostly a week in the life of our modern detection and monitoring systems, but of course everyone is immediately sucked into the topic of armageddon. The more we can detect, the more insignificant or only mildly interesting objects we will become aware of. So get used to it. There’s going to be asteroid news in our future other than “END OF WORLD NIGH.”

A 27-inch asteroid

Shameless clickbait headline.

Depends on how fast it’s going.

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".

[–] [email protected] 5 points 3 weeks ago

Headline is tricksy, first mention of "asteroid" (referring to the small one) isn't with the descriptor "massive", but the second one is.

They just added the one that's gonna miss so they could get "massive" in the headline.

Also, one can play around with asteroid impacts with this fun little tool.

Only goes down to 1m, so larger than what it was. Iron core and I put it to 100km/s (fastest you can in that, default being like 17km/s) dropped it in Siberia, and it blew up 53 km above the ground. Tried again with switching angle to straight down and...

Can you please course correct? Earth has a nasty infestation that needs some clearing

[–] [email protected] 1 points 3 weeks ago

Infestation is the correct term

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.

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

Feel free to criticize the Jerusalem Post for other reasons, they deserve it, but their reports on near-miss asteroids where they compare their size to random things is always amusing.

No banana for scale?

[–] [email protected] 5 points 3 weeks ago

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 😺😸

Boo you whore

Fucking teasing bitch.

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

Is this even about space?

[–] [email protected] 7 points 3 weeks ago (2 children)

A mile consists of a lot of feet

A foot consists of many inches

Easy peasy.

How many eagles in a mile in freedom units?

We talking wingspan or beak to tip?

Butt to silencer
