Pallene (moon) facts for kids
Pallene is a tiny moon that circles the giant planet Saturn. Scientists first spotted it in 2004. Pallene is quite small, only about 4 kilometers wide. It orbits Saturn between two much larger moons, Mimas and Enceladus.

What is Pallene?
Pallene is one of Saturn's many moons. It's considered a very small moon, sometimes called a "moonlet." Its small size, about 4 kilometers across, means it's shaped like a potato, not a perfect sphere like Earth's moon. This is because it doesn't have enough gravity to pull itself into a round shape.
Where Does Pallene Orbit?
Pallene orbits Saturn in a special place. It travels between the orbits of two much bigger moons: Mimas and Enceladus. Mimas is famous for its giant crater, which makes it look a bit like the Death Star from Star Wars. Enceladus is known for its icy geysers that shoot water into space. Pallene's path is influenced by these larger neighbors.
How Was Pallene Discovered?
Pallene was discovered by the Cassini Imaging Science Team in 2004. The Cassini spacecraft was a very important mission that studied Saturn and its moons for many years. It took amazing pictures and gathered lots of information.
The Cassini Mission
The Cassini-Huygens mission was a joint project by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI). The Cassini spacecraft launched in 1997 and reached Saturn in 2004. It spent 13 years orbiting Saturn, exploring its rings, moons, and atmosphere. It helped us learn so much about this amazing planet.
Finding Tiny Moons
Finding a small moon like Pallene is a big challenge. Cassini's powerful cameras were able to spot it in images taken from orbit around Saturn. Scientists had to carefully look at many pictures to find such a tiny object. This discovery showed how many secrets Saturn still holds.
Why Are Small Moons Important?
Even though Pallene is tiny, it helps scientists understand the Saturn system better. Small moons can be leftovers from when the solar system formed. They can also be pieces of larger moons that broke apart. Studying them helps us learn about how planets and moons are made.
Connection to Saturn's Rings
Some small moons, like Pallene, are thought to be connected to Saturn's famous rings. They might help shape the rings or even be made of material from them. Scientists are still studying these connections to understand the complex dance between Saturn, its rings, and its many moons.
