There is no planet in our solar system that has 100 moons. In fact, the planet with the most moons is Saturn, which currently has 82 confirmed moons.

It's important to note that:

* New moons are constantly being discovered. So, Saturn's moon count could change in the future.

* The definition of a "moon" can be debated. Some smaller objects orbiting planets might be considered "moonlets" rather than full-fledged moons.
