Okay, so 104 Aquarii is a star that's very far away from us. It's in a group of stars called the Aquarius constellation, which kind of looks like a person pouring water out of a jug. People like to look at stars because they are pretty and sometimes tell us things about the universe.
Now, 104 Aquarii is a special kind of star called a binary star. That's because it's actually two stars orbiting around each other. Think about a merry-go-round with two horses going around and around. That's kind of what's happening with this star.
Scientists have been studying this star and they have found that one of the stars is bigger than the other one. It's like having a big elephant and a small mouse holding hands and spinning around. The big star is pulling the smaller star around as they spin.
These two stars are also very hot, which means they are shining super bright. They are making a lot of energy that we can't see with our eyes, but scientists can detect it using special instruments. This energy is important because it helps us understand more about how stars and the universe work.
So basically, 104 Aquarii is a special star that is actually two stars orbiting around each other, and scientists study it to learn more about the universe.
