What is the solar point?

Solar Point

I don't know. I know what the subsolar point is, it's the point in a orbit (of an object around a planet) where the sun is as close to overhead as it can get. Am I close?

if this is true then the solar point would most likely be noon on earth. or at scale (since he said a satelite to the sun) it could be when the center of the galaxy is closest to overhead earth of course that could be the galactic point. im not really sure either.
