"Tyche is suspected to be four times the mass of Jupiter with an orbit
around 15,000 times further from the Sun than Earth's, and 375 times
further than Pluto's. It will probably be composed mainly of hydrogen
and helium, with an atmosphere just like Jupiter's. Professor Whitmire
added that the planet-in-waiting will have its own moons, like other
outer planets, and its surface will be covered in colorful spots, bands
and clouds. The Wise data also revealed that Tyche is four or five times
warmer than Pluto, at a prediceted -73C (-99F). "The heat is left over
from its formation," said Prof Whitmire, "It takes an object this size a
long time to cool off."

In a few months time, we could be back to the good ol' nine-planet solar
system, courtesy of the giant Tyche. Watch this space. "http://newsfeed.time.com/2011/02/15/a-nine-planet-solar-system-once-m...

Perhaps we can assume those IR narrow bandpass FOV(frame of view)
exposures of perhaps not more than 60 seconds by the HSO will be
sufficient to locate the giant Tyche. If need be, several minute
exposures shouldn’t be all that time consuming in the search for the
slow moving Tyche that’s supposedly huge and shivering around 35 K
(ideal target for the HSO, even if it’s carbon lampblack albedo of
less than .05).

“This image is a 32 s exposure taken with the 4.2 m William Herschel
Telescope on La Palma using an 890 nm narrowband filter. The image was
taken at 03:03 UT on the 3rd of August when the Earth and Sun still
were on opposite sides of the ring plane. The opening angle of the
rings was ~0.2 degrees.”

“The Herschel Space Observatory covers the wavelength range from 55 -
672 microns. This corresponds to the maximum of emission for black
bodies in the range from 5-50K approximately. Hence Herschel is be
best suited to observing icy outer solar system objects and cool and
cold dust in the universe, both in the rest frame and redshifted. A
prime objective has been to study the formation of galaxies in the
early universe, as cool dust is an excellent tracer of star formation.
The Herschel range is also the one at which cool and cold gases emit
their strongest lines, meaning that Herschel is also a superb
laboratory for examining the chemistry of planetary atmospheres and of
the interstellar medium.”

I kinda doubt Tyche at 4 Jm is as cold as 35K (unless it’s as old as
the universe), so that should make it almost glow in the dark (so to
speak in terms of IR imaging). JWST (when and if it ever flies)
should outperform Herschel IR sensitivity by at least another
magnitude if not by 4 db, plus offering a thousand fold better
resolution. Add the StarShade mission to this and we should see
whatever rogue exoplanets or whatever moons the size of Earth or
smaller.

Now that's almost an exoplanet, and if any of those captured moons are
Earth sized could even be enough Goldilocks qualified to count as
planets that just so happen to have a common moon that's 4 times the
mass of Jupiter.
