NASA Day Photo: Cassini Satellite Captures 5 Moons of Saturn | Science News



On July 29, 2011, the NASA and ESA's Cassini Spacecraft Direction and Camera took this photo, capturing five moons of Saturn right from the ring. The moons on the left are the small moons of Saturn Janus and Pandora, which are 111 miles and 50 miles (179 and 81 km, respectively) transverse.

In the middle is a glossy moon with a diameter of 313 miles (504 km) Enceladus. [19659002] The second left is Mimas, 246 miles (396 km) wide, visible next to Rhea.

Cut off from the right edge of the frame, Rhea is Saturn's second largest moon with a width of 949 miles (1528 km) in diameter.

NASA's astronomy picture of the day coincides with the news that 20 new moons have been discovered around Saturn.

This brings the total amount of Saturn's external satellites to 82 known moons.

A NASA spokesman says, "Since Jupiter's total lunar value is 79, Saturn is the new king of the solar system."

The newly announced satellites are very small, 3 miles (5 km) transversely, and most are in retrograde orbits inclined to Saturn

Two of the programn moons are closer to n

The more remote retrograde moons and one of the programmable moons take more than three years to complete the orbit.

Dr. Scott Sheppard, of the Carnegie Institution for Science, says: "The study of the orbits of these moons can reveal their origin, as well as information about the conditions around Saturn at the time of its formation."

The outer moons of Saturn appear to be grouped into three distinct groups.

Two of the newly discovered bulbs fit into a group of outer moons with slopes of about 46 degrees, called the Inuit group, as they are named after Inuit mythology.

These moons may have once represented an ancient larger moon, broken in the distant past.

Similarly, the newly announced retrograde moons have similar slopes to other previously known retro-class satellite moons, indicating that they are also likely fragments of the once larger parent moon that was shattered.

These retrograde moons are in the Norwegian group, their names coming from Norwegian mythology.

One of the newly discovered retrograde moons is the most famous moon around Saturn.

Dr. Shepherd says, "This kind of clustering of outer moons is also observed around Jupiter, indicating that strong collisions have occurred between moons in the Saturn system or with external objects, such as passing asteroids or comets. "

How to help NASA name the 20 new Saturn moons:

Participants can submit their suggested names for the new Saturn moons in which they tweet their ideas and reasons for @SaturnLunacy.

The inclusion of photos, works of art and videos is also highly encouraged.

NASA also wants competitors to include the hashtag #NameSaturnsMoons.

The contest ends on Friday, December 6th.
