The first swiveling orbit suggest all orbits do but in a very small way.
The swivel of Mercury came from the difference of strength of gravity
by distance that is changing in between gravity centers.. Sun and first planet.

Orbits are in slightly different gravity strengths
this determines swivel degree which can be too small
to see at this time but by required time we might
begin to see...

So, you are basically saying that orbits are mostly, nearly perfectly circular- which is what I have been saying.

So, if they are not going to give me credit- maybe they will give you credit- good luck.

And you are wrong. Yes, the eight planets have reasonably circular orbits except 
for Mercury. But most large asteroids and dwarf planets like Pluto do not have 
circular orbits, and there are more of them than planets. Moreover, there are 
over 700 comets that have been observed, and NONE of them have an orbit that is 
anywhere close to circular.

Part of this is selection bias -- to be notable an orbiting object must be 
observed. But if an inner solar system object had an eccentricity comparable to 
a long-period comet (0.97-0.99), it would never have been observed by humans 
because it would have melted or broken up long ago (coming so close to the sun). 
So the only objects in highly elliptical orbits are far from the sun and have 
periods of hundred to thousands of years (or longer, c.f. the newly discovered 
"Planet 9"); Halley's comet is a rarity (period only 75 years).

	Mathematically, the set of circular orbits is minuscule
	within the set of all possible orbits. That is, the vast
	majority of all possible orbits are not circular at all.

In addition, most extrasolar planets whose eccentricities are known have values 
more than ten times that of earth.

	It's remarkable (and sad) that you have opinions on so many
	things you clearly know nothing about. You really should
	learn how to recognize when you don't know something.

This is a saying "no circles are perfect, and therefore PI is varing" :)

I think James may have been referring to apsidal precession, first 
noticed in the orbit of Mercury. But saying that it applies to all 
orbits is only stating what's already well known.

Look at the speed of the Earth in orbit. It accelerates by the very small
then it is taken back. The increase in speed is micro for the Earth orbiting
around the sun. Look at the orbital strength of gravity only accelerating by
the smallest difference that creates ellipses (that swivel)

Nope - that's completely incomprehensible.

Yes, the tiny amount of acceleration does for the large part show the Earth's amount of ellipse-id-ness.

Tom, I'm just "what iffing" you know that.  What about the percentages of mass though in our solar system?  Mercury is small and closest and is unstable.
