But planetary bodies that formed in different parts of the solar system generally have different isotopic compositions, so different that the isotopic signatures serve as «fingerprints» for planets and meteorites from the same body.

The content of the air is made of two sets (CO2 anthropic from emissions)(t) and (CO2 natural)(t); the lifetime of the molecules is the same for both sets and is known to be in the range 3 to 7 years; once a lifetime is assumed the (CO2 anthropic from emissions)(t) and its delta13C can be computed to get (CO2 natural)(t) and its isotopic signature; this is done for several assumed lifetimes of CO2 molecules in the air.
