“Did you know that the closest planet to the sun, Mercury, has a tail much like a comet? You can see it in photographs taken with special filters to highlight sodium blown off the planet by the solar wind….”

My notes: This is so awesome! I have never heard of this before. Has anybody else?

I don’t recall ever hearing about that. I might have thought and just forgot about it.

I have never heard of it before. Pretty cool though. And it's length is 100 times the earth's diameter! That's 791,750 miles! Makes you think, how long will it take before Mercury is just wittled away!
It has to be getting smaller all the time, as this is blowing off it's surface.
