Himalia, also known as Jupiter VI, is the largest irregular satellite of Jupiter. With a diameter of around 140 km, it is the sixth largest Jovian satellite, after the four Galilean moons and Amalthea
Composite of six New Horizons images of the possible Himalia ring. The double exposure of Himalia is circled. The arrow points to Jupiter.
The rings of Jupiter are a system of faint planetary rings. The Jovian rings were the third ring system to be discovered in the Solar System, after those of Saturn and Uranus. The main ring was discov

…In September 2006, as NASA's New Horizons mission to Pluto approached Jupiter for a gravity assist, it photographed what appeared to be a faint new planetary ring parallel with and slightly inside Himalia's orbit. Because the small (4-km) moon Dia, which had a similar orbit to Himalia, had gone missing since its…
A schema of Jupiter's ring system showing the four main components. For simplicity, Metis and Adrastea are depicted as sharing their orbit. (In reality, Metis is very slightly closer to Jupiter.)

The upper image shows the main ring in back-scattered light as seen by the New Horizons spacecraft. The fine structure of its outer part is visible. The lower image shows the main ring in forward-scattered light demonstrating its lack of any structure except the Metis notch.
Image of the main ring obtained by Galileo in forward-scattered light. The Metis notch is clearly visible.
