it does make complete sense though. the closet object that constantly orbits the sun will be the closest to every object that constantly orbits the sun on average.
this new close-up photo of the sun is pretty cool...they say each of those kernels are about the size of texas..

i was watching a pretty cool special about the big bang last night. one of the weirdest things was when it was describing the incredible rate at which the universe expanded within the first second, faster than the speed of light. they measure everything in planck time. in the first billionth of a billionth of a second of planck time, the universe expanded from the size of a subatomic particle to the size of a baseball, which is the equivalent of a golf ball expanding to the size of the earth. and there are more units of planck time in a second than there have been seconds that have elapsed since the big bang 13.8 billion years ago. that's crazy.

It will get within 9 or 10 Sun-diameters of the "bottom" (the Sun's surface) which seems pretty far when you put it that way, but from up here on Earth it's practically all the way down.

I was just listening to a podcast last week that talked quite a bit about the Parker probe. Fascinating stuff--it's going to get so close to the sun that there's a large amount of time where it won't be able to communicate with earth, so it'll be flying entirely by programming with no chance for mission control to course correct. It's going to be flying through the solar wind as it's being ejected, basically. Wild stuff.
it does make complete sense though. the closet object that constantly orbits the sun will be the closest to every object that constantly orbits the sun on average.
