Yes indeed, a much bigger and hot sister or mother planet to that of
Venus is caught roaming about on the loose (unbound from any star):
And if the discovery team is right about CFBDSIR2149's age, the body
is likely a planet, with an average temperature of 806 degrees
Fahrenheit (430 degrees Celsius), researchers said.

The free-floating object, called CFBDSIR2149, is likely a gas giant
planet four to seven times more massive than Jupiter, scientists say
in a new study unveiled today (Nov. 14)
http://en.wikipedia.org/wiki/CFBDSIR2149-0403

Of course planets smaller than this one or those existing as moons of
the really big ones like CFBDSIR2149 are going to remain as undetected
until our existing astronomy instruments can be fine-tuned and/or
improved upon, that is unless these nomad items should pass much
closer to us than 10 ly. Detecting a rogue/nomad Earth sized planet
that s only giving off 64 TW plus whatever heat artificially generated
that could easily double that to 128 TW, as such is going to be really
hard to spot unless getting within a light year, because the smaller
and cooler the item is making their unbound existence extremely
stealthy.

ESA s Herschel and eventually our spendy JWST should spot lots more of
these wandering nomad planets, that by some astrophysics accounting
are as populated as 1e5 per star, though mostly of orphaned planets
much smaller than Saturn and of everything else down to planetoids as
small as Ceres. Out of every hundred wandering nomads should be at
least one of those offering a viable Earth and/or Venus sized planet.

Not too likely, unless it came into close proximity of the Earth. Such a
planet would enter at superorbital speed, pass perihelion, and then fly
off into space, never to return.

Or it could make a low differential speed glancing blow off our moon
or Earth, and stick around.

No -- if it comes from extra-solar space, it would have a hyberbolic
orbit relative to the Sun. By the time it got to i AU from the Sun, it
would have considerable velocity, obviating "a low differential speed
glancing blow off our moon."

It is unlikely that such an encounter would even come close enough to
any of the planets to cause a problem -- especially if it entered with
high inclinations to the Ecliptic.

Indeed, introducing any nomad mass the size of a Jupiter is going to
distort the living hell out of most everything, even if merely passing
through the outer solar system. A small addition such as Venus or
even as little as that of an icy planetoid of 7.4e22 kg that could
easily have sucker-punched our planet, creating the likes of the
Arctic ocean basin and establishing our seasonal tilt, as such
shouldn't be taken lightly, because the evidence is quite clear that
planets and moons have survived such enormous encounters, though no
telling how many didn't survive and became the debris of our vast Oort
cloud.

Low speed rear-end merging encounters of the glancing blow sorts
should not be all that common, through at least somewhat probable none
the less. Our moon is proof-positive of how a planetoid can survive
massive encounters that would have easily killed off every form of
evolved or deposited life, and the seasonal tilt of Earth along with
its Arctic ocean basin is yet another good example of a planet
surviving such horrific encounters of the lithobraking kind that could
be subsequently captured as our moon.
