What does the dipole moment really represent?

If all the multipole expansions apart from the monopole is zero, then is the charge density spherically symmetric?

What does the monopole/quadrupole moment of the Earth signify?

Why is dipole the simplest source in electrodynamics?

Far away from a charged conductor, the field is like a point charge. Where's the point located?

Multipole Expansion: Electrostatics

Why there is no dipole gravitational wave?

Hexadecapole potential using point particles?

Can one force the electric quadrupole moments of a neutral charge distribution to vanish using a suitable translation?
