Selene is a major planet.

Planet Selene orbits Earth and Sun on the ,
not on Earth's equator. Selene always falls toward
the Sun, never away from the Sun. Several people,
including Isaac Asimov and other scientists, have
already decided that the Moon is really a planet.


That's probably a significant fact in support of the Moon as a planet in
a binary planet system with the earth.

I am not the originator of the co-planet or convex orbit concepts. The
ecliptic observation is probably a significant fact in support of the
orbit of Selene as a planet.

I made CAD drawings of the orbits of the Moon and the Earth, and these
were posted on alt.binaries.pictures.astro.
Due to lack of interest I removed them. Perhaps you saw them. The 12-gon
shaped orbit of the Moon is completely convex, There are no circles,
loops or concavities in the orbit.

I'll try to re-post the .tif file images. If I post them I'll place a
note on this thread. The freeware/shareware program, irfanview.com, is
the best for displaying images that I have found.

I the CAD model rendered images the binary planet system can be seen as
co-planets and there is no circular orbiting of the Moon around the
Earth visible at all. It is pretty clear that Selene is still a separate
planet.

My conclusion or hypothesis is that the Moon was a planet in a similar
orbit to Earth's, and that as the eons went by the Moon gradually
approached the Earth in an orbit similar to Earth's. The Moon went
closely past the Earth on the inside of Earth's orbit so slowly or with
a small speed differential that the mutual attraction caused the two to
counter orbit. I suspect that the combination was gradual. The
elliptical orbits may have become more even in time.

It is clear from the visual evidence of the CAD drawn curvatures of the
Moon's orbit that it is a separate planet and that it is only
co-coincidently a captured entity that became a satellite of Earth.

There has been a computer dynamic mass properties modeling of a
hypothetical collision. That was really impressive. I wish that was
available to see again. Who made that computer demonstration video of
Selene and Earth?

Is there a possibility that the capture of Selene was merely a near
miss, and that a violent collision did not occur? There may have been
some transfer of materials from rings to both planets.

Image notes:

The red dashed line is a 12-gon to illustrate the near and far points of
the Moon's orbit from the Sun. Note that the yellow line that is the
Moon's orbit around the Sun is completely convex and +/- 240,000 miles
nearly circular. The blue dash-dot line is the orbit of the Earth, and
the blue dashed lines illustrate the maximum and minimum distances of
the Moon's orbit from the sun. The circle around the Earth is the line
of intersection of the Moon's Sun orbit and the Moon's Earth orbit.

The drawings were posted along with more explanations several months
ago. The CAD model was made in MicroStation V8 CAD program at a
precision of +/- one foot. The distances drawn were nominal: 8,000
miles, 2,000 miles, 93,000,000 miles, and 240.000 miles. All orbit lines
except for the Moon's and the 12-gon were drawn as circles, and the
edge-on views show the circles as similar ellipses. The Moon's orbit was
drawn as a B-spline curve to simulate a plotted mathematically
calculated curve. The respective speeding up and slowing down of the
planets' velocities around the opposite planets of the Sun, nor the
possible precessions of their orbits, was not factored in.

Observe the curvature of the convex line of the Moon's orbit in the
edge-on views. The Moon's orbit, that is, Selene's orbit around the Sun
as a separate planet can be visualized.
