Asteroid 349507 (2008 QY) is around 1.2 kilometers in diameter, or around 1,000 capybaras – large enough that an impact event (which won't happen now) could be a worldwide catastrophe.
While the asteroid is traveling too far to pose any risk to the Earth, a possible impact event with it could become a worldwide catastrophe.
I'd switch, but I've been on the Capy system my whole life, and it's just much more intuitive for me. Everyone knows how long a Capybara is. How fucking long a meter is? Beats the fuck out of me, maybe a half cap?
And we'll misapply it as well. The asteroid isn't the size of 1000 capybaras, it's as wide as 1000 capybaras lined up. Assuming it's roughly spherical, it's actually closer to the size of 524,000,000 capybaras.
Asteroids can be wildly non-spherical though, in shapes way different than capybara non-sphericalities, so it's not only misapplied but likely also nonsensical... unless, it's a giant capybara shaped asteroid.
Look I think the joke is as funny as anyone else but the "unit" is an animal most of the Americans its meant to lampoon most likely wouldn't have even heard of.
This is a measurement unit. A bit unconventional, but it's not any worse than using three grains of barley, dry and round, placed end to end lengthwise, or the length of King Henry I's foot.
Which is why it’s silly to represent the size of the asteroid in capybara lengths. We should be representing it in capybara volumes or masses. Probably be something more like 1 billion capybaras.
But how many Olympic swimming pools is that? Or is that a unit of volume... sorry, I think I'm looking for the number of football fields, yes how many of those is it in diameter?
I don't think they know how volume calculations work. When I read 1000 Capybaras, I though "huh, that's not actually that big", until they say it's actually the diameter or that much capybaras.
EDIT: I did some pocket calculations and it seems like 1000 capybaras can fit into an around 13 capybara diameter sphere.
Okay. That literally told me nothing about the size of the asteroid, but that's pretty funny and I bet it gets people to click the link.
I also like how OP's article also appears to take a dig at fear mongering around asteroids by talking about how the asteroid isn't coming near earth, it really isn't a problem, if it hit earth it'd cause untold devastation but you really dont need to be afraid because it's not gonna hit us ever.
Because humans are notorious for not being able to estimate area and volume. Pretty much anything but length. People can visualize an Olympic swimming pool. They cannot visualize an acre or hectare.
But mostly, it's because units are about communicating. They need to provide understanding to the user. That's why feet and inches are so useful as units. They're real to everyone.
Let me give you an example.
DC fast chargers operate at 250 kW. I can do all kinds of physics with that number. How long it would take to boil a cubic meter of water. How fast can that accelerate a rock. All the things.
That's not very helpful though. It doesn't tell me anything real in my life.
Now, I'll tell you that that number will trip the main breaker of 5 typical houses. That's better, but I don't really know how much a house is.
What I do know is how hot an oven is when running on full blast.
250 kW is more than 80 ovens running on full blast.
That's about as good an intuitive understanding of that number as I can get.
