Our solar system has 8 large planets. If we leave the earth aside, 5 of them (Mercury, Venus, Mars. Jupiter, Saturn) have been known for more than 2 millennia and were previously associated with gods. After the invention of the telescope, Uranus, Neptune and Pluto were added. They are not visible to the naked eye. Pluto has since been downgraded to a minor planet.
