How about reconsidering upon a nearby 2 star system like Sirius?

I understand that Sirius-b was once upon a recorded time that of a
red-giant sun prior to going into it's white-dwarf phase.

What are the planetary survival odds, plus that of the vast Sirius Oort
cloud populations of icy proto-moons if not icy proto-planets?

The intentions of this continuing rant is besides if not in spite of
our NOT having walked upon the moon;
There has nearly always been other significant life that's perfectly
capable of their having been situated upon Venus (at least on behalf of
accommodating ETs), and otherwise of that little issue about our moon
that's actually perfectly good for so many things once the LSE-CM/ISS
is up and running and of sufficient robotics having been efficiently
and safely deployed, as for those items functioning on behalf of
science, clean energy and for the very salvation of humanity. Unlike
what we've been told over and over by all of those folks supposedly
having 'the right stuff', there's nothing the least bit insignificant
nor without good if not of essential cause and rewards pertaining to
our moon, and unlike those opposing absolutely anything and everything
that represents change, I simply can't hardly think of anything but
positive thoughts about our moon as well as for Venus as being yet
another perfectly good thing for the greater salvation of Earth and
advancement of humanity. How can anything pertaining to our moon or
that of Venus become such a taboo/nondisclosure negative that which
such topic/authors deserve getting stalked, bashed and/or banished?

That's rather downright odd. Here I'd honestly contributed as to the
matter of an astronomy fact that Sirius-b was likely if not
astrophysics-101 somewhat required as once upon a time being a
red-giant, and lo and behold, gosh darn if it seems as though all of
the topic lights went out. Why the heck is that? or perhaps what's so
gosh darn taboo/nondisclosure about the Sirius star system?

Hunt for Sirius C and Substellar Companions

According to Duchner and Brown (2000 preprint -- in postscript), three
analyses of the proper motion of Sirius found a perturbation in the
orbit of Sirius B with a period around six years (Ch. Volet, 1932;
Walbaum and Duvent, 1983; and Benest and Duvent, 1995). The analyses
did not resolve whether the perturbing body orbits Sirius A or B,
although dynamical simulations suggest that stable orbits exist around
both stars at circumstellar distances up to more than half the binary
system's closest separation of 8.1 AUs (Daniel Benest, 1989). Because
ancient astronomers believed that Sirius was red in color as late as
2,000 years ago, some investigators wonder if the system may have a
third stellar component, Sirius C, with about five percent of Sol's
mass that implies a spectral type M5-9 in a six-year elliptical orbit
around Sirius A (Benest and Duvent, 1995). A recent search for faint
companions using the Hubble Space Telescope found no supporting
evidence for a large Jupiter or brown dwarf sized object, although the
observed positions of Sirius AB -- Gl 244 AB -- differed from published
orbital elements (Schroeder et al, 2000).

4. The majority (about 80 t0 85%) of stars in the solar neighborhood
are binary stars.
Single stars like our sol are clearly within the minority.

Orbits can be stable in triple star systems after all the three stars are
bound, but for how long? According to my computer analysis a three
component system is only stable if two of the components are less that 1/100
the mass of tyhe primary. This is a numerical simulation based on eulers
integration to give the solution to a multi-body problem. If the mass of
the second or third component is too high then the third component is
eventually ejected from the systym. This occurs with three nearly equal
masses, one gets ejected.

I doubt if this quasi-stable planetary orbit will be there for ever. But
how stable is "stable". If the separation is big enought between the three
or two primaries then I would of thought stability would be very high, and
as nearly as stable as our solar system.

It is believed by some astronomers that the Sun is bound in a binary with
another star some way off that may be a black dwarf or neutron star.

Chris no-spam;
I'm truly impressed, or has your recent operation and subsequent
medications taken hold as planned?

In the case of the Sirius star system, can we suppose that such a
"third component" could have been Sirius-c/Venus (as none the less
bringing along a spare moon for the ride)?

Is there anything within your "computer analysis" that excludes our
binary association with the Sirius star system?

BTW; walking upon our moon is still a real stretch that apparently
comes without the possibility of viewing Venus nor Sirius as otherwise
easily and unavoidably imaged from the perspective of a nearly coal
like dusty darkness and reactive lunar surface, not to mention there
being a lack of any R&D/prototype fly-by-rocket lander in addition to
the highly unreasonable lack of the unavoidable secondary/recoil
photons of near-blue and absolutely zilch worth of near-UV recorded
photons via unfiltered Kodak moments, as such there's a wee bit of an
insurmountable problem that's proving squat on behalf of those Apollo
missions. However, there's been other life upon Venus as having
absolute loads of vertical as well as geothermal energy to burn, even
though as such will not actually burn within such an O2 starved
environment as having been hosting a perfectly rational township of a
fairly substantial community that includes a bridge and a few of your
standard rigid airships plus accommodating that nifty UFO Park-n-Ride

Really?

How so, whom & why.

I would consider this highly unlikely!

Good luck,

6. Martin 53N 1W,
The entire universe is "highly unlikely", especially the singular
BIG-BANG part. So what's your anti-ET and thus anti-God and otherwise
pro-everything mainstream notions or ulterior motives this time around?

Why are you so anti-Sirius?

Are you also a devout bigot against whatever's associated with the
Sirius star system?
