对小行星尘埃粒子轨道演变的数值模拟表明，地球被嵌入一个由小行星尘埃组成的环日圈中，并在其尾流中永久存在尘埃云。这可以解释红外天文卫星（IRAS）观测到的黄道光云的不对称性。环共振捕获和随后释放的尘埃颗粒可能提供了一种机制，通过这种机制，碳质材料从小行星带被运送到地球。
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.
