S/2003 J 10: Jupiter's Tiny Moon!

S/2003 J 10 is a moon, but not a big, famous one like Earth's Moon. It's a tiny little rock that goes around Jupiter, the biggest planet in our solar system. Jupiter is so huge that it has lots and lots of moons, and S/2003 J 10 is one of them! It's like a tiny pebble next to a giant beach ball.

This little moon lives far, far away in space, orbiting the giant planet Jupiter. Jupiter is the fifth planet from the Sun, and it's a gas giant, meaning it's mostly made of swirling gases. S/2003 J 10 circles around Jupiter at a distance of about 12.7 million kilometers. That's like driving around the Earth 318 times!

Scientists think S/2003 J 10 is made of rock. It's not very big, only about 2 kilometers across. That's smaller than most towns! Because it's so small and dark, it's very hard to see, even with big telescopes. It's like trying to spot a tiny ant on a giant football field.

S/2003 J 10 is a fast mover! It takes only about 2.5 Earth days to zip all the way around Jupiter. That's super quick compared to Earth's Moon, which takes a whole month to go around us. This speedy moon is always on the go, completing its journey around Jupiter again and again.
