Apart from the Earth, the Moon and Mars chlorine isotope measurements have been done on a variety of other solar system bodies. Most significantly, these measurements were made on meteorites that were found on Earth. Apart from these, chlorine isotopes were determined on meteorites that originated from the planetoid 4 Vesta and were found on Earth, in situ in the coma of comet 67P/Churyumov-Gerasimenko and in the atmosphere of Venus with ground-based telescopy from Earth.
