I wonder how this might affect Copernican heliocentric astronomy against a
fixed stellar background ...


Was that aimed at you-know-who?

I'm sure I can't imagine who you refer to, Jonathan ... I was merely musing
about our central star, swinging around a 3 million km diameter circle (with
us orbiting the same baryentre admittedly, still bathed in its glow). Since
yon barycentre represents the Solar System's centre of mass, one assumes it
maintains a fixed trajectory with respect to the stellar background and that
it is only the sun and planets' distance from said point which varies over
time according to the relative angular and radial disposition of the
planets. I suppose the sun still disappears each night and reappears the
very next day, only to be seen bobbing up and down over the horizon
throughout the year. Thank god for the relative view - be hopeless trying
to grow prize toms without it (I favour watering mine with human urine, but
don't tell her indoors for god's sake) )
