Seems incredible that after 4.5 billion years there’d still be any gas left to spew. Mercury a latter addition to the solar system?

Stiff drops out of the Oort Cloud all the time ~ undoubtedly Mercury gets its fair share of the booty ~ which would evaporate just like everything else.

Think of this as a time dilation effect cometary effusion factor!

Another way to look at this is to think of our Solar system is "normal" with the requisite number of gas giants inward of Jupiter ~ EXCEPT they've already been boiled down to their rocky cores.

Still some juice in there though ~
