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.
A light-year (abbreviation: ly), sometimes referred to incorrectly as a light year, is a unit of length used informally to express astronomical distances. It is approxi ..more definition+
