of icy objects.

The potential jumbo Jupiter would likely be a world so frigid

A distant icy Oort Jupiter of 2e27 kg that’s interacting with a solar
system of 2.02e30 kg at the orbital distance of 1 ly (9.46e15 meters)
is only worth an influence of 3e15 N. Its orbital velocity of less
than 120 m/sec gives this item a very long orbital cycle, and
obviously much longer if it’s operating as an elliptical
configuration.

To put this into some perspective:
The current (sun ~ pluto) gravitational force of attraction:
1.989e30 and 1.305e22 kg at 5.906e12 m = 4.964e16 N

Thereby Pluto is something better than 16:1 greater influence than any
1 ly distant 2e27 kg icy Oort cloud item. In other words, it would
require a 16+ Mj icy Oort item at one light year in order to match the
gravitational influence that Pluto has to offer.

What this interpretation means is that our NASA and their usual cabal
of insiders are once again trying to pull off yet another tactical
ruse, as a media distraction or divergence that’ll keep some of us
distracted from whatever’s really affecting our local space and
getting worse every year.

current (solar system ~ Sirius) gravitational force of attraction:
2.02e30 and 6.9615e30 kg at 8.1365e16 m = 1.417e17 N

So, if there’s anything perturbing our comets and asteroids into the
inner solar system, it’s probably not caused from any stealth external
Oort item unless it’s a small neutron star or black hole of at least .
1e30 kg or somewhat greater mass.

It would take something like a nearby 0.1 Ms brown dwarf to cause the
similar amount of comet/asteroid disturbance that is being suggested,
and only if its orbiting well within 2 ly from us most of the time. A
16 Mj (3e28 kg) item of 1 ly or less distance might conceivably do the
trick, although an icy item of that kind of volumetric mass should
have been hard to miss (certainly much harder to miss than little red
Sedna). It's actually more likely we have a visiting brown dwarf or
spent neutron core from the Sirius system that's causing us grief, but
then I’ve been suggesting such for several years and getting nowhere,
all because Sirius has been mainstream taboo or forbidden to speak of.

Will, the bigger the planet's diameter, the more likely it will eclipse
a star in an given period of time.
One interesting thing is how its gravity would displace the star's image
as it got near to its position in the sky; although its gravity would be
nowhere near as powerful as the Sun's the great distance between the
giant planet and the Earth could mean that it would slightly bend the
star's light with its gravity to a degree that could be seen from a
space telescope.
If that did occur, you could start figuring out the mass of the planet
by its gravity field.

It there's an undetected planet out there that's 4x
the mass of Jupiter, there's no telling what else is
out there that we've missed.

Let's just hope that if you do see it eclipse a star, you don't see a
Einstein Ring, because what's out there isn't a giant planet, it's a
very small black hole: http://en.wikipedia.org/wiki/Einstein_ring

Or is there a better way to detect celestial objects
in the Oort cloud, or in other areas distant from
a star?

It's quite true that it could hardly do that, if its orbit is not
eccentric like that of a comet (or, of course, the 12th Planet of
Zecharia Sitchin).

But this is actually a good question - wouldn't even a Jupiter
orbiting beyond Sedna transit stars? With a very long period, of
course, it would be rare for it to start transiting a new star, but
eventually it would reveal itself by crossing the Milky Way.

Perhaps we need to get our spendy and way past due JWST up and
running, because that thing should do a super fine job of detecting
brown dwarfs or even icy Oort planets the size of our moon out past 1
ly.

That would all depend on the phasing of its approach. If it came through
the Solar System on the opposite side of us, it would barely cause a
ripple. The 1/R**2 effect.

Yeah, but if it's in orbit around the Sun, and the orbit works like some
sort of giant comet that brings it inside of Earth's orbit at long
intervals...with as large as its presumed mass is...the whole solar
system should look like a giant game of pinball, with all the planets
being in odd orbits from being affected by its huge gravity field during
its prior passages close to the Sun. I mean, we are talking about
something massive enough to hurl Jupiter or Saturn into very eccentric
orbits, or actually tear them apart via tidal stresses if it got close
enough to them, or pull their moons out of their orbits and make them
into planetary bodies in their own right in strange orbits around the Sun.
The fact that the tiny gravitational influence between Earth and Venus
has led to a tidal resonance that causes Venus to face its same
hemisphere towards Earth each time it passes us in orbit argues that at
least those two planets have been in stable orbits for a very long time
indeed.
There's also the flip side of this; such a planet passing repeatedly
through the orbit of Jupiter is sooner or later going to get close
enough to Jupiter to get its perigee screwed up to the point where it
flies right into the Sun rather than whipping around it, despite its
greater mass than Jupiter.
That would generate one hell of a solar event when it occurred, but it's
bound to occur with enough orbits.

There's also the problem of where such a massive planet would come from.
The solar system seems to show a pretty regular planetary size
distribution as it formed from the original solar nebula. You have the
four inner rocky planets forming one group of increasing and decreasing
mass, then the asteroid belt, then the four gas giants of steadily
decreasing mass as you get to the area where solar heating is low enough
the the gases that surrounded them wouldn't boil off during their
initial accretion.
Some sort of super-sized gas giant at the distance this theory proposes
just doesn't make sense from a point of view of planetary accretion...
if it _is_ out there it must have been captured from another stellar
system, or be the product of a mini-accretion disc that never got big
enough to form a star in its own right. I have a hard time believing
that somehow the Sun got close enough to it while moving at the correct
angle and speed to let it establish a orbit around it, rather than
simply deflecting it away into interstellar space or having it fall into
the Sun itself.
If it was a failed proto-double star that formed when the Sun did from
the same accretion disc, then you would expect its orbit to be a lot
more circular than this theory proposes.
