ELI5: Explain Like I'm 5

Kepler-1625b I

Kepler-1625b i is a very special planet that is located very far away from Earth. It's so far that if we wanted to visit it, we would have to travel for many years using a super-fast spaceship!

Kepler-1625b i is special because it's part of a system with two stars, just like the famous Star Wars planet Tatooine! But instead of two suns, this planet has one sun and one much smaller star that orbits around the bigger one.

The planet itself is very large, much bigger than Jupiter in our solar system. Jupiter is the biggest planet in our solar system, and Kepler-1625b i is even bigger than that! Because this planet is so big, it's known as a gas giant. It doesn't have a solid surface like Earth or Mars, but it's mostly made up of gas, like hydrogen and helium.

Recently, scientists have discovered something very exciting about Kepler-1625b i. They think that it might have one or more moons orbiting around it! This is very unusual because gas giants like Jupiter usually have many moons, but this planet is so far away from us that it's difficult to see any moons that might be there.

To find out more about Kepler-1625b i and its possible moons, scientists used a powerful telescope called the Hubble Space Telescope. They carefully watched as the planet passed in front of its star, and they noticed something strange. Just as the planet was about to go in front of the star, there was a tiny dip in the amount of light that the scientists were seeing. This dip could be caused by a moon passing in front of the planet at the same time!

This is a very exciting discovery because it could mean that there are one or more moons orbiting around Kepler-1625b i. If this is true, it could give us clues about how planets and moons are formed in other star systems. But we will have to keep studying this fascinating planet in order to learn more!
