[Rockhounds] The "nine-banded armadillo", a new astronomical unit of measurement :-)

[Paul]

I found the use of a nine-banded armadillo as a unit of length a
bit strange in the below article.

Asteroid the size of 33 armadillos to pass Earth Sunday - NASA
Asteroid 2023 FL2 is 35 meters, which is as much as almost 33
nine-banded armadillos lined up tail-to-snout. However, it won't
hit us, and armadillos might even be more dangerous.

I have to wonder how many armadillos would represent an
extinction-level event?

In another article, asteroid 2023 CX1, in said to be twice the size of
a super bowl trophy. https://www.jpost.com/science/article-731426 .

A corgi and baby elephants are used yet another article,

and camels used in yet another article,

Are raurakl uesd in Australia to measure the size of asteroids?

I guess reporters are getting bored with the metric system.
