Approximately how long until this white drawf [which used to be the

long enough for this to happen?

The temperature falls off somewhat exponentially... looks like it would
take hundreds of billions of years to get that cool, maybe trillions.
But it has all the time in the world (or the Universe), since it seems
likely the Universe will not ever cease to exist, but will just keep
cooling down and expanding forever.
