Small grains of dust, released by comets and asteroids, fill the space between the Sun and the planets. To learn how they behave near the Sun, we combined data from four spacecraft that either sense single grains hitting them or picture the sunlight scattered by the grains. Together, these observations build a consistent picture of where the dust sits and how it moves in the inner solar system, which helps us understand dust around other stars and grains coming from beyond our solar system.
