Pallene (moon)

Pallene is a very small natural satellite of Saturn. It is named after one of the Alkyonides of Greek mythology, and is also designated Saturn XXXIII. Its orbit lies between the orbits of the larger M

Rings of Saturn

Saturn has the most extensive and complex ring system of any planet in the Solar System. The rings consist of particles in orbit around the planet, ranging from micrometers to meters in size, and are

…light by the Cassini spacecraft enabled the Cassini Imaging Team to discover a faint dust ring around Saturn that shares Pallene's orbit, now named the Pallene Ring. The ring has a radial extent of about 2,500 km. Its source is particles blasted off Pallene's surface by meteoroid impacts, which then form a diffuse…

The full set of rings, imaged on 19 July 2013, as Saturn eclipses the Sun from the vantage of the Cassini orbiter, which is 1.2 million kilometres (0.75 million miles) from Saturn. Earth appears as a dot at 5 o'clock, between the G and E rings – with its brightness artificially exaggerated in this photograph.

Simulated image using color to present radio-occultation-derived particle size data. The attenuation of 0.94-, 3.6-, and 13-cm signals sent by Cassini through the rings to Earth shows abundance of particles of sizes similar to or larger than those wavelengths. Purple (B, inner A Ring) means few particles are < 5 cm (all signals similarly attenuated). Green and blue (C, outer A Ring) mean particles < 5 cm and < 1 cm, respectively, are common. White areas (B Ring) are too dense to transmit adequate signal. Other evidence shows rings A to C have a broad range of particle sizes, up to m across.
