Scientists use special telescopes to find other solar systems. They look for tiny changes in starlight that tell them a planet is there. Some of these planets are rocky like Earth, and some are giant gas balls like Jupiter. A few might even have water on them!
- The first planet outside our solar system was found in 1992.
- Scientists call these faraway planets “exoplanets.” There could be billions of other solar systems in our galaxy alone.
- That means there are more planets out there than grains of sand on a beach!
