    In the 4.5 or so billion years the earth has existed the core is estimated to have cooled by 300 degrees F. From that, assume the core will still be about the same when the sun expands and swallows the earth.

    Two or three billion years.

    Longer than anyone currently alive on Earth or the next 30 generations need to worry about.
