During the course of its evolution, the Sun has accreted substantial quantities of material in the form of asteroids, comets, planetesimals and proto-planets. This debris is poor in hydrogen and helium and has substantially enriched the metallicity of the solar surface which must consequently be higher than that of the unobserved core. ... The solution may also explain the Faint Young Sun paradox and the inclination of the solar equator relative to the ecliptic. ...
