Description

Ío on the left aproaching the planet. In transit, Callisto (left) and its shadow (right).

We could see the very faint grey penumbra surronding Callisto’s shadow .

Projected onto Jupiter’s surface, the moon’s dark umbral shadows, decrease in size with satellite’s distance from Jupiter.

Io’s shadow appears the largest and boldest, while Callisto's umbral shadow appears as a relatively tiny black dot, surrounded by a very faint grey penumbra.
