Sounds like physics-101, and of what a given red giant phase of a
given star like Sirius B might have accomplished.

There's also those pesky run-ins of all sorts of nasty stuff (hot or
icy cold) going bump in the night, such as interstellar Oort cloud
interactions and/or of those items that haven't quite figgured out how
to avoid gravity.

Yes the Ort Cloud and the Kuiper Belt and the placement of Uranus/
Neptune in an area of the solar system where they could not have
formed according to current theory is something of an embarassment.
The solar wind was treated with absolute scorn before Mariner II and
IV actually measured it. Tectonic plate movement was treated with
contempt when it was called continental drift.

Life is imperfect. My area of interest is a former gas giant with an
exposed planetary core. They should exist around red dwarf stars where
the orbit of the planet is short. It should have a mass between 1-1/2
and 4 earths (or more) and it should be very nearly almost entirely
made of iron except for the last 1/4 of its radius. Except for the
mass part and the red giant part, Mercury might be a candidate in our
solar system because it could be the remnant of a failed gas giant
from the planetary nebula. If true there should be some rather exotic
materials laying about the surface. Remember we have been completely
surprised every time we have sent a space probe to another world. Not
every other time, not every third time or one in ten. Every single
time we have sent a space probe to another world we have been
surprised. Not once has a space probe sent back completely expected
results from what was 'thunked up' by thinkers. Every single time the
gold ribbon went to the doers. Noone has sent a probe to Mercury
because we already 'know' what is there. I believe a probe should be
sent to every world in the solar system before anyone says we 'know'
what is there.

But all that costs a mountain of money. We need a real engine for
spacecraft that doesnt cost a pound of gold for every pound it puts in
earth orbit.

We've had the necessary decades as well as all the necessary loot,
except for such having been literally blown on our mutually
perpetrated cold-war(s) and then especially because of 911 and the
subsequent Iraq fiasco as of lately (about all that's left is WWIII).
There's has been no shortage of loot or the required time, whereas
instead there's a rather nasty shortage of honesty and the necessary
balls for kicking the right kind of butts into action.

I agree with your analogy, of there being more than a few extremely
old and rogue sorts of red or brown dwarfs along with their binary
companion iron orbs nearby, possibly even a few large enough rogue
planets along with their moons without benefit of any sun to light or
otherwise warm their interstellar way.

Here's what I'd posted on a fully related topic: "Planetary Heat
Losses / Brad Guth"

Supposedly a red giant phase of a substantial 5+ solar mass star like
Sirius B is good for at least a robust 500 million years, after which
it rather quickly becomes a little white dwarf.

How about Venus new, Earth so so watever and Mars as old or older than
our slaty old moon:
Supposedly by some mainstream accepted physics estimate of the Mars
core still offers 1727°C according to "Fei and Bertka, Science; 2005",
although there's still no apparent surface measurement of what such an
extent or cache of geothermal energy could be leaving Mars at any
great pace (perhaps it's less than one mw/m2), so if its core is
actually that hot it must be extremely well insulated.

"The martian geothermal heat flux (q) has never been measured"
http://epubl.ltu.se/1402-1757/2006/48/LTU-LIC-0648-SE.pdf
Most if not all of the geothermal heat flux figures for Mars are those
of SWAG estimates via remote science and a good portion of applied
physics math, as providing perfectly valid conjectures based upon Mars
being essentially the same age as Earth and of whatever X average
density, of which may or may not be the case. Of course the
geothermal heat flux of our moon hasn't been directly measured either,
and we haven't even figured out how to establish a viable science
platform of instruments situated within the moon's L1, So what's the
difference, when we can't even via remote science compare the heat
flux of Earth to that of our own moon?

Who would be all that surprised if Mars were old enough and thus
becoming ice to the core?

What if our salty old moon, as having been a once upon a time icy
proto-moon, as coming in from or simply as having passed through our
icy Oort zone, would actually be somewhat newer or older than Earth,
especially age skewed if having once been owned by Venus and each of
those orbs as having been ejected by the Sirius B red giant phase.

Perhaps orphan or foreign exchange planets and of whatever viable
proto-moons are not all that unlikely, especially if our solar system
were cruising nearby enough and at just the right time when half a
binary had been going red giant.
