Numerical simulations of the orbital evolution of asteroidal dust particles show that the Earth is embedded in a circumsolar ring of asteroidal dust, and has a cloud of dust permanently in its wake. This could account for the asymmetry of the zodiacal cloud observed by the Infrared Astronomical Satellite (IRAS). The resonant trapping and subsequent release of dust particles by the ring may provide a mechanism by which carbonaceous material is transported from the asteroid belt to the Earth. 
Observational confirmation of a circumsolar dust ring by the COBE satellite
ASTEROID collisions are an important source of the dust particles in the zodiacal cloud1–3. These particles spiral in towards the Sun under the influence of drag forces4–6 and, in passing through theExpand

Asteroid collisions and cometary outgassing produce grains and dust that cause to fill the interplanetary space. The particles are temporarily trapped into orbit of the Earth to develop a circumsolarExpand
Co-orbital Asteroids as the Source of Venus's Zodiacal Dust Ring
Photometry from the Helios and STEREO spacecraft revealed regions of enhanced sky surface-brightness suggesting a narrow circumsolar ring of dust associated with Venus's orbit. We model thisExpand

Imaging of a Circumsolar Dust Ring Near the Orbit of Venus
Sensitive photometric observations from the STEREO mission confirm the existence of a dust ring at the orbit of Venus, and the radial density profile of this ring differs from the model used to describe Earth's ring in that it has two distinct steplike components. Expand
Structure of the Earth’s circumsolar dust ring
Interplanetary dust particles from comets and asteroids pervade the Solar System and become temporarily trapped into orbital resonances with Earth, leading to a circumsolar dust ring. Using theExpand
Migration of small bodies and dust to near-Earth space
