From “Textbooks will need to be updated“ to „Jupiter is now believed to be about five miles narrower at its equator and 15 miles flatter at its poles.“

I don’t know what I was expecting, but a whopping 0.02% smaller polar radius is not it. What were the uncertainty ranges on previous measurements/estimates? I can’t read the full Nature paper.
>At the 1-bar pressure level, we find a polar radius of 66,842 ± 0.4 km, an equatorial radius of 71,488 ± 0.4 km and a mean radius of 69,886 ± 0.4 km, which are 12 km, 4 km and 8 km smaller than previous estimates, respectively
