I will discuss our on-going work to define the chemical profile of stars in the solar-age, solar-metallicity cluster Messier 67. The remarkable chemical similarity of the first confirmed solar twin in M 67 to the Sun (Önehag et al. 2011) made us tentatively suggest a solar origin as part of this rather unique cluster. But can the dissimilarity of the orbits, in particular the current high Galactic latitude of M 67, be reconciled with this hypothesis? And what about the idea that solar-like abundance profiles reveal the presence of terrestrial planets? I will argue that M 67 holds key observables for open questions related to planetary, stellar and Galactic astronomy.
