The Sun's diameter is approximately 1,391,000,000 meters in length, which is over 100 times the approximate diameter of the Earth (12,756,200 meters).
The approximate size of a nucleus is about 1 femtometer (1 x 10^-15 meters). This makes it about 100,000 times smaller than the size of the atom as a whole.
No, the typical size of a nucleus is on the order of femtometers (10^-15 meters). The size of a nucleus is much smaller than 0.006 meters.
The distance from the nucleus to the electron in an atom is typically on the order of several thousands of times the diameter of the nucleus. This is due to the small size of the nucleus compared to the electron's orbit.
The size of an atomic nucleus is typically on the order of femtometers (10^-15 meters), which is much smaller than the size of the atom itself. The nucleus contains protons and neutrons tightly packed together in a small volume at the center of the atom.

An atom nucleus is typically on the order of femtometers (10^-15 meters) in size. A cell is much larger, with most human cells ranging from 10 to 30 micrometers in diameter.
