Heliocentric Distance Dependence of Zodiacal Light Observed by Hayabusa2#

Kohji Tsumura, Shuji Matsuura, Kei Sano +21

Zodiacal light (ZL) is sunlight scattered by interplanetary dust particles (IDPs) at optical wavelengths. The spatial distribution of IDPs in the Solar System may hold an important…
