Imagine finding a planet that rains glass. What about one covered in hot lava? Or a planet that glows pink?
It might sound like science fiction, but these planets exist! They’re all exoplanets, which are planets outside our solar system. Exoplanets usually orbit, or travel around, stars. Scientists are finding new ones all the time.
More than 30 years ago, scientists used a powerful telescope to spot the first exoplanet. Since then, telescopes have gotten better and better. Now scientists have discovered more than 6,000 exoplanets!
