I cannot find a single cite that explains this, not even on NASA
website or google scholar searches, could you point me to a cite
please? And yes, orbits are elliptical.

http://www.wxresearch.org/papers/orbit2004.htm

is close enough for folk music!

And close enough to satisfy that I am right. "A common misconception
is that
the center of the solar system is the Sun and the planets orbit
around the
Sun. This is somewhat factual. The four inner planets orbit the Sun,
which
is in orbit about the center of gravity of the solar system. The
five outer
planets are the only true orbiters of the center of gravity of the
solar
system. Therefore, the Sun should not be considered the center of
the solar
system, the center of gravity of the solar system should be
considered the
center of the solar system."

We DO orbit the sun............. The earth and the sun both orbit
their system's centre of gravity which happens to be within the sun.

Those two sentences of yours contradict each other. Don't you
understand that ?

You do realise your first post on this was totally wrong "The Earth
doesn't circle the Sun - both the Earth and the Sun orbit the centre of
gravity of the Solar System."

1. (disregarding Michelle's mistaken use of circled - your second comment
in that sentence shows you understand what she meant and was stating it
was wrong) The earth DOES orbit (or "circle" to explain it loosely).

2. The earth and the sun DO NOT orbit the centre of gravity of the solar
system. Each planet has its own orbital connection to the sum according
to where the centre of gravity is between them. The centre of gravity for
the earth-sun connection is within the sun. Take a look at an animation
of the sun and the earth orbiting. because of where the centre of gravity
is the orbit of the sun is way different to that of say Pluto. You will
see that the earth does orbit the centre of gravity as well as orbiting
the sun.

When I asked for a cite proving the earth didn't orbit the sun you gave
me cites that disproved your claim and totally proved mine. As I said, I
don't see your point of argument - which was "the Earth doesn't circle
the sun".

And the winner is . . . Feitlebaum!
