Is Venus Concentrating Interplanetary Dust Toward Its Orbital Plane?

Abstract

By use of observations of zodiacal light, the symmetry plane or plane of maximum density of interplanetary dust at elongations of 32° to 50° from the sun has been found to be closer to the orbital plane of Venus than to the invariable plane. This suggests that the plane of maximum density in this region is being gravitationally perturbed closer to the orbital plane of Venus.
