How do we know how massive the Sun is? Well we know how distant it is by direct measurement. Based upon its apparent size and its distance we can calculate its real size (volume). As far as its mass, it is made up mostly of the two lightest elements known, so any change to that will only make it more massive.
Moreover there is a minimum size for a star, otherwise its gravity will not be sufficient for nuclear fusion.
How small do you need the Sun to be for it to circle the Earth? Care to make a calculation? How would your ‘mini star’ undergo nuclear fusion? Why does it look so big and why is it measured to be so distant?
One needs to discount all Science, reason, and measurement if they wish to make the Sun small enough to circle the Earth.
And to overturn the Enlightenment as well.
(And these folks claim they're not anti-science!)

How do you verify this a proven concept? Is is not verifiable at all! It is conjecture and assumption absed on observations from here on earth, as well as from spacecraft. You realize, of course, we don't even know what the Earth is made of past 8 miles deep!
gravity will not be sufficient for nuclear fusion.
Hydrogen to helium, eventually to iron, and so forth. Theory, conjecture, and an assumption that the sun has been burning for Billions of years. Circular reasoning. The gravitational collapse model was widely accepted, until Millions of years were required for Darwinism, which prompted an change in theory to Nucler Fusion. However, problems aboud with this model as well, including the shrinking size of the sun, angular momentum of sun & planets, etc.
How small do you need the Sun to be for it to circle the Earth?
About the same size as the moon, I suppose.
Why does it look so big and why is it measured to be so distant?
Don't they look to be the same size in the sky? Don't they both rise & set from our perspective?
I am not asserting geocentrism any more than you are, I am just pointing out assumptions and problems with the heliocentric model, just as you are with the geocentric model. I tend towards Helio, myself. :)
