The number of planets that orbit a star can vary widely. In our solar system, there are eight planets orbiting the Sun. However, many other stars in the universe have been found to host multiple planets, with some systems containing as many as seven or more. Overall, discoveries from exoplanet research suggest that most stars may have at least one planet orbiting them.
