The Bohr radius (a0 or rBohr) is a physical constant, approximately equal to the most probable distance between the proton and electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.2917721067×10^−11 m.
Lunar distance (LD), also called Earth-Moon distance is a unit of measure in astronomy. It is the average distance from the center of Earth to the center of the Moon ..more definition+
