Why do we know the position of the nucleus well compared to that of an electron?

Well, the nucleus is over 1836 times heavier.... relative to the electron, the position of the nucleus is well-known. Relative to the atom as a whole (which is mostly empty space), and particularly relative to the entire world, we don't really know the position of the nucleus that well.
In general, the heavier the object, the more well-known its momentum is, because its wave characteristics become less significant.
