Exoplanets are planets outside our solar system. Some orbit bright stars, while others drift through space alone – these are called rogue planets. Scientists have discovered more than 5,800 exoplanets but believe billions more exist in the Milky Way galaxy. Some are rocky, like Earth, and some are gas giants, like Jupiter. There are even scorching lava worlds and strange, squishy planets as light as foam, showing how diverse the universe can be.
