The Sun could reduce the activity by 90%, and the planets get 10x closer to compensate the reduced light.
Interesting how a star can be "ejected" from a galaxy :

Sorry, I cannot think of a better place to put this, just not the last thread to which I was responding, which was someone else's:
I have been listening to comforting cadences as I work.
Arguably, "The Spooning Song" isn't a cadence. It did not help me work.
The next one was "Baby Marine." I always have difficulty with the first line: "Talkin' to my daddy on his dying bed."
I wasn't able to say goodbye to mine until he was cold.
I hope that everybody is having a great day.

Allow me to introduce the Inverse Square Law: "the intensity of an effect such as illumination or gravitational force changes in inverse proportion to the square of the distance from the source." https://www.lexico.com/definition/inverse_square_law
So, if you are twice as far from a source of light, noise, or other radiation, you receive one-quarter as much energy. If the sun decreased its output by 90%, planets would need to get 3.16 times closer to to compensate.

You are absolutely right.
I made the comment so fast I forgot about square meter law, a so basic thing.
I just used the proportion relation of size variation (like height/diameter of Moon or SUN) and distance, but forgot to consider both dimentions to make the calculation.
3,1262277660168379 times closer to be more exact.

This article explains that as the sun burns hydrogen and helium sinks to the center

Don't recall where I snagged this from:
"if you leave enough hydrogen long enough, it'll begin to wonder why it is there. We are Universe experiencing itself.
"
Maybe Slashdot's UNIX fortune cookie?
