Requiem for elliptical orbits.

When behind the Earth, the space telescope moves backwards,
which is contrary to orbital expectations of continuous
forward motion. http://www.sr.bham.ac.uk/xmm/moments3.html
Perhaps the telescope oscillates in front and behind the Earth
according to Donald Hamilton's proposal:

It must be an embarrassment for the University of Birmingham to be
serving a page that includes (more than once) the misspelling of the
word "satellite" on http://www.sr.bham.ac.uk/xmm/moments3.html

Donald L Hamilton is a well known crank, registetred at

"behind the Earth" relative to whom? Mars does not have a
periodically retrograde orbit, nor does a terrestrial satellite. You
don't now how to read a map. You can't even think self-consistently.

"Since we can define angular momentum in terms of linear momentum
times a distance, it seems sensible that angular momentum is also
conserved."

Idiot.
Homogeneity of space + Noether's theorem = conservation of linear
momentum.
Isotropy of space + Noether's theorem = conservation of angular
momentum.
(Compactified dimensions in M-theory would symmetry-break conservation
of angular momentum at their chacateristic scale(s).)

Those rectangular maps of the earth don't actually represent its shape.


Now you tell me. But, all seriousness aside, the "orbits" are
directional, that is pointed easward. Even near polar orbits
do no deviate much from the easterly direction. John Curtis

What the hell does "behind the Earth" mean?

I dare you to find a situation in orbital motion wherein both angular
and linear momentum are simultaneously conserved. Linear momentum is
not always conserved, and definitely not in the orbital plane. Or am
I misunderstanding what you are actually saying here?

To be fair, linear momentum of the system taken as a whole
is conserved.

Behind the Earth is a location on Earth's orbital path.

Oh. So you were talking about the satellite's path
around the sun?

Yes. Large difference between masses and narrow
difference between the paths around the Sun may produce
the visual effect of a satellite "orbiting" the Earth.
