It's from last month's issue of American Scientist.

Toward the end of the article, that author says that the
configuration of extrasolar planets aroung the star 55 Cancri has a
region of stable orbits

that will allows a planet to exist in the habitable zone around it's
sun, where the temperature is just right for liquid water to exist.
Since the
whole point of the article is that solar systems are "full," ie. that
all stable orbits are typically inhabited, the author is clearly
suggesting that the chances are quite good of actually finding a
planet in that region, eventually.

The first sentence in that article was certainly not written by anyone
who knows Kepler's work or indeed that of the pre-Copernican or
heliocentric astronomers -

"In 1605, Johannes Kepler discovered that the orbits of the planets
are ellipses rather than combinations of circles, as astronomers had
assumed since antiquity."

Care to correct it ?.

The geocentric astronomers  posited the Equant for the Keplerian
refinement whereas epicycles were employed to resolve the main
Copernican argument based on retrogrades -

"Copernicus, by attributing a single annual motion to the earth,
entirely rids the planets of these extremely intricate coils [spiris],
leading the individual planets into their respective orbits
[orbitas],quite bare and very nearly circular. In the period of time
shown in the diagram, Mars traverses one and the same orbit as many
times as the 'garlands' [corollas] you see looped towards the
centre,with one extra, making nine times, while at the same time the
Earth repeats its circle sixteen times "  Kepler  refering to diagram
on page 86 -

It is amazing that there is an overlooked orbital component to the
Earth's motion,which can visibly be extracted from the motions of the
Equatorial rings of Uranus yet nobody wants to touch it -

The change in orientation of the rings with respect to the central Sun
is 100 % certain along with the nature of the change in accordance
with Keplerian precepts.Before you ponder other solar systems perhaps
it is much better to adding the major orbital component to our own
planet and specifically replacing the pseudo-dynamic of variable axial
tilt with the explicitly observationbal orbital change.

The moon librates on a much shorter period than that.

The new orbital component based on referencing orbital motion against
the Sun is too magnificent a motion to ignore.yet you have no feel
for it -

The change in the Equatorial rings with respect to the Sun is in
accordance with Keplerian orbital geometry hence it is quite seperate
to axial rotation/orientation.The application of the same principle to
the Earth's orbital motion leads to a simple working principle that a
location will turn through 360 degrees with respect to the Sun over
the course of an annual orbit.

I would have expected an MIT engineer to intepret the images correctly
but judging from the youtube sequence you responded with,obviously you
have not.The addition of a new orbital component is a major departure
from the pseudo-dynamic of variable axial/Equatorial inclination and
unfortunately,for whatever reasons,nobody in the entire newsgroups are
up to the challenge even with sequential imaging of another planet
allied with graphics demonstrates its existence explicitly,not even an
inference required,but a clear and unambiguous observation.
