How Large Do Proms Get?

Proms are enormous. Below is a fantastic image shot by Martin Wise with a scaled-down Earth superimposed to show the size.

Note the spicules in Martin's image... Incredible from a solar-head perspective. Here's a link to Martin's site: https://spaceweathergallery.com/indiv_u ... _id=167467

I knew it was getting hotter on Earth! ...

Great capture, though, and certainly puts things into perspective size-wise.....(!)

Then again, Earth is actually quite small if you think of it. About 40 000 km around. Quite many people drive more in a year.
