I really don't know where you come up with some of what you say. There is a "supermoon" and while the term originated with astrology, not astronomy, it does exist.
Nope. The term "supermoon" is NOT an astronomical term used by any astronomer or astrophysicist. I also think you may be confusing the 14% larger with its diameter, and not its area?
Thank you for pointing out something I that's actually posted in my quote. As I acknowledged, the term originated in
astrology but is now pretty much accepted as a colloquial term for "perigee-syzygy" which astronomers use. As evidence of that fact I posted an article from NASA using the term "supermoon".
Your contention was that the supermoon does not exist and implied that belief of its existence in the 21st century is akin to believing evil spirits cause sneezes. This is incorrect.
As to the second part, I really don't understand what your getting at. If my math is correct, a 14% increase of the surface would be an increase of about 6.8% to it's diameter, so I'm still wondering where you got the 1.5% maximum figure.
