Nitpick---

It is not cold or warm in space. It is a near vacuum. Hot or cold refers to
the amount of kinetic energy in the particles of matter (I can't remember • what
that "shaking" is called maybe random kinetic energy?) There's just not • enough
bits of stuff in space for caloric energy to be transferred. The problem in
space is actually getting rid of excess heat because solar radiation and such
that hits an object (like a spacecraft) heats it up, but there is no where • for
that heat to dissipate. One way is a heat sink, another is a radiator fin • that
gets hot enough to radiate the heat out as em radiation.

That is assuming that you're close enough to a star to be getting that kind of
solar radiation. Out in deep space, say, Pluto's distance from the Sun, there
is basically no solar radiation.  Thus, space acts as a giant heatsink and
pulls heat away from you at an alarming rate.  That's why it appears very cold
in space.  Definitions of "Hot" and "cold" are all relative anyway.

Regardless of how close or how far you are to a sun, you still need lots and
lots of insulation, both to keep your warmth in, and to keep solar radiation
from baking you like a potato in an oven.
