"The first planet to be discovered was Uranus by William and Caroline
Herschel on 13 March 1781. It was discovered by the fact that it showed
a disk when viewed through even a fairly low powered telescope. The
only other planets which have been discovered are Neptune and Pluto.
These were predicted using ingenious mathematical arguments based on
Newton's laws of gravitation and then observed near their predicted
locations. "
http://www-groups.dcs.st-and.ac.uk/~history/HistTopics/Neptune_and_Pluto.html
Uranus was discovered as a planet using the periodic times argument of
Kepler -
Epitome Of Copernican Astronomy by JOHANNES KEPLER
Finally by what arguments do you prove that the centre of the Sun which
is at the midpoint of the planetary spheres and bears their whole
system - does not revolve in some annual movement,as Brahe wishes,but
in accordance with Copernicus sticks immobile in one place,while the
centre of the Earth revolves in an annual movement.
Argument 10
" The 10th argument,taken from the periodic times, is as follows; the
apparent movement of the Sun has 365 days which is the mean measure
between Venus' period of 225 days and Mars' period of 687
days.Therefore does not the nature of things shout out loud that the
circuits in which those 365 days are taken up has a mean position
between the circuits of Mars and Venus around the Sun and thus this is
not the circuit of the Sun around the Earth -for none of the primary
planets has its orbit arranged around the Earth,as Brahe admits,but the
circuit of the Earth around the resting Sun,just as the other
planets,namely Mars and Venus,complete their own periods by running
around the Sun."
Johannes Kepler
The powerful tool where orbital motions are compared and arranged
geometrically in terms of position from the Sun required no reference
to the background stars but Newton introduced the background stars and
managed to disguise the Ra/Dec conception based on 3 years of 365 days
and 1 year of 366 days as 365.25 days -
"The periodic times with respect to the fixed stars, of the planets and
earth revolving about the sun, in days and decimal parts of a day."

Have any single one of you an idea what vandalism this amounts to,not
the theorists who will believe anything,but genuine astrophotographers
who may not wish the astronomical discipline to be completely dominated
by junk ?.

Unfortunately Pluto has such a small mass that its gravitational influence
on other planets is indefectible. The discovery was more a matter of chance
and close study of the photographs.

That, and it is by far the brightest trans-Neptunium object known.

The article shows how the history of planetary discovery is flexible in
the empirical cult ,once used in highlighting the effectiveness of the
dynamicists can justl as quickly and quietly be buried when they
decide Pluto is no longer a planet.
Dynamicists have yet to learn how the original arrangement of planets
is derived from the periodic times arguments based on orbital
comparisons.
