Answer me this one; which direction is the Sirius Oort cloud rotating

Define in what field of reference you would measure it - first I heard
Sirius had an Oort cloud...


I'd thought that most all significant star/solar systems offered some
degree of an Oort cloud and/or at least a Kuiper belt that's chuck full
of nifty little orbs and debris, thus I'm assuming a massive star/solar
system like the Sirius solar system should have managed at least a
little something similar that's perhaps going in the general direction
as Sirius-b.

Are you thinking that perhaps our's is the only such star and planetary
system that's hosting the likes of Kuiper belt and Oort cloud items
worth considering? If so, why are we so special?


I never said that - I deal with definites, not maybe. Seeing as Sirius
is a double, all bets are off

Obviously our best instruments are put off by the vast intensity of
Sirius-a and even of Sirius-b is actually extremely UV-a/b/c bright,
thus whatever's of a Sirius Kuiper/Oort likeness is lost somewhat
within the glare and/or having otherwise been overwhelmed by the local
amount of available energy that we can't seem to squint hard enough to
see of whatever there's to behold.

So, if given the Sirius debris is most likely going along for the ride,
such as moving along with the somewhat vertical direction of rotation
as that established by Sirius-b, whereas if that's to be given in any
rotational relationship to us; which direction is the orbit of Sirius-b
traveling with regard to the rotation of our Kuiper belt and Oort
cloud?

As we get closer to one another (my research swag thus far points to
roughly every 105,000 years), I'd have to imagine that the orbit of
Sirius-b should become a whole lot less vertical and more horizontal,
and certainly more elliptically distorted or stretched out and
unavoidably better aligned to that of our disk of planets and outer
debris, that which includes the somewhat large items as icy Sedna.

This is somewhat more than a little interesting:
http://www.siriusresearchgroup.com/a...f_heaven.shtml
"Pluto, the outermost planet, went through its perihelion of its highly
eccentric orbit which lies within Neptune's orbital path and is
inclined by approx. 17 ° relative to the general planetary plane.
Pluto's orbit is oriented towards the common center of gravity
between Procyon and Sirius. It is remarkable that the orbital
relationship between Pluto (248.02172 tropical years) and Sirius B
(49.6 years) is almost 5 to 1. Also, the approx. 17 ° deviation and
direction seem to have a strange relationship to the 16.6° declination
of Sirius with respect to the celestial equator."
