    That would be the "local interstellar cloud (LIC)". The density of the LIC is about 0.3 atoms per cubic centimeter (mostly hydrogen). The temperature of these atoms is, on average, about 7000K (6,730 C).

    Empty space by itself doesn't have a temperature: it's the things in that space that have a temperature. Those things might be atoms, or photons, or other things.

    The temperature of space beyond the heliopause is 3 Kelvins (around -270 Celsius).

    The temperature in outer space is 2.73 Kelvin (-270.42 Celsius, -454.75 Fahrenheit). This is actually the temperature of Cosmic Microwave Background Radiation, which is spread throughout the entire universe.

    Add - space is not a 100% vacuum. Physical particles can absorb and release energy. Cosmic radiation is also not exactly the same everywhere.

      Cosmic radiation is higher the closer you get to stars. It's high inside galaxies.  The 2.73K of the CMBR is the temperature BETWEEN galaxies.
