When you decide to join the rest of humanity and drop the ridiculous
sidereal justification on which Newtonian ballistics applied to
planetary motion,then you have a chance of becoming astronomers and not
remaining cretinous cataloguers.You do indeed justify the Earth's
rotation directly to both the Sun and stars -

"Each solar day the Earth rotates 360º with respect to the Sun.
Similarly the Earth rotates 360º with respect to the background stars
in a sidereal day. During each solar day, the motion of the Earth
around the Sun means the Earth rotates 361º with respect to the
background stars."

You freaks still talk of the return of the Sun to the same
position,give yourselves choices you do not have as axial rotation
through 360 degrees is an independent event (for those who have a
shread of sanity) yey you follow after an awful lapse of reasoning that
began with Flamsteed/Newton.

You freaks infer constant axial rotation in 23 hours 56 min 04 sec not
because it is correct but because you give yourselves astronomical
choices that do not exist,this one -

Be a fucking man instead of a creep,check that this procedure and
statement by Flamsteed (Newton built on it) is incorrect and adjust
your position to seeing that the Equation of Time equalises the
variations in your geocentric return of the sun to the same position
and then translate it into independentand constant axial rotation with
a heliocentric framework -

"Flamsteed used the star Sirius as a timekeeper correcting the sidereal
time obtained from successive transits of the star into solar time, the
difference of course being due to the rotation of the Earth round the
Sun. Flamsteed wrote in a letter in 1677:-

.... our clocks kept so good a correspondence with the Heavens that I
doubt it not but they would prove the revolutions of the Earth to be
isochronical... "

I have given you the only math you will ever need to correct this
Flamsteed stupidity and Newtonian insincerity and I will not repeat it
again here for it now goes to more responsible people who recognise
that people should not be subject to pretension and insincerity.

Otherwise I am content to leave you celestial peeping toms to carry on
believing that you are astronomers as I turn to a world that is more
than ready to accept that cataloguing and theorists creeps have been
insincere long enough.Enjoy your celestial sphere based on the sidereal
value but know that you are an isolated bunch.
