Abstract
EVIDENCE about the motion of zodiacal dust particles has been obtained recently by myself and Ring1 when we measured the wavelength position of the Fraunhofer Hβ line (λ 4861 Å), in the evening zodiacal light, as a function of elongation from the Sun in the ecliptic plane. An attempt was made to interpret the data in terms of a model in which the dust particles were in circular Keplerian orbits about the Sun and had a spatial density distribution of the form r−a.
