Abstract: In recent years, the research on moderately volatile elements in solar system bodies has sparked a wave of interest. As a member of moderately volatile elements, zinc (Zn) and its isotopes are good indicators for tracing the high-temperature evaporation process. Hence, the Zn isotope is considered as an ideal tool to study the evolution of solar nebula and planets in the planetary science. Here, we have systematically summarized the Zn isotopic compositions of various meteorites and planetary reservoirs, and have provided a comprehensive overview on the zinc stable isotope researches of different types of meteorites and extraterrestrial samples (carbonaceous chondrites, ordinary chondrites, enstatite chondrites, angrites, iron meteorites, stony-iron meteorites, lunar meteorites and Apollo samples, Martian meteorites, Vesta meteorites, etc.). Those researches were mainly concentrated on the controlling factors of zinc isotope composition in different meteorites and planets and the indication of zinc isotopes for the nebular processes and planetary processes in the solar system. At the same time, we have briefly discussed the fractionation mechanism of zinc isotopes in the formation and evolution process of the solar system, and have explored the prospects and development trends of zinc isotope researches in the planetary science on the basis of previous researches.
