Okay kiddo, so you know how we have a big moon up in the sky, right? Well, sometimes there can be little friends that hang out near the moon too, called trojans.
These trojan moons are kind of like little moons that follow the big moon around in space. They are like tiny buddies that are always by the moon's side, just like your teddy bear or favorite toy is always with you.
The reason why they are called trojans is because they are named after a famous ancient story called the Trojan War. In that story, there were some friends of a prince named Trojan who were always by his side no matter what happened. They were loyal and stuck together, just like the little moons do with the big moon.
Overall, trojan moons are just like little extra companions that the big moon has, and they don't really cause any trouble. They just like to hang out and be good friends.
