How Do Scientists Find Exoplanets?

Planets are large objects that orbit or circle around a star, like the Sun! Planets can be made up of rocks and gases. Our Solar System is made out of 8 planets that are made up of either gas or rocks. Rocky planets are called terrestrial planets and gaseous planets are called gas giants. Planets take billions of years to form. Exoplanets are planets that are outside of our Solar System in the Milky Way. Exoplanets are detected using very powerful telescopes like the James Webb Telescope. Exoplanets orbit around their own stars in a Solar System. Scientists are trying to find life in other galaxies by focusing on exoplanets that are similar to Earth.
