The discipline overlaps with astronomy and chemistry. The term may refer to studies within both the Solar System and the interstellar medium. The investigation of elemental abundances and isotope ratios in Solar System materials, such as meteorites, is known as cosmochemistry, while the study of interstellar atoms and molecules and their interaction
