Information from Solar System Dust

Interstellar gas and dust can enter the solar system and become incorporated in interplanetary dust. Measurements of the isotopic abundances of elements in individual interstellar dust grains within interplanetary dust can be made, and give results that are anomalous for the solar system. These results can be used to indicate the origin of these grains in different dust-forming sources. Although the fraction of solar system dust that has an interstellar origin is very small, these grains include a great variety of materials. These are interstellar dust grains that have survived their travel in the interstellar medium and incorporation in the formation of the Solar System.
