We are entering a new era of the chemical characterization of exoplanets and solar system objects. Many surprises assuredly await us and will need interpretation. Even in the solar system, fundamental aspects of Earth’s elemental composition remain poorly understood. I will briefly recap the astrochemistry of planet formation, summarize some key knowledge and problems of the elemental composition of planets and planet-forming material, and outline the value and future of measuring elemental compositions in planet-forming and planetary environments. Measurement techniques of elemental composition in protoplanetary and debris disks are of particular importance to the field, and I will focus in particular on recent work using sub-millimetre spectra of protoplanetary disks and optical spectroscopy to study the surface “contamination” of accreting early-type stars.
