Our solar system is made up of a star (the Sun), nine planets, more than 125 moons and a bunch of comets and asteroids. The nine planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Mercury is the closest to our Sun – Pluto is the farthest. An easy way to remember the order of the planets is to memorize a rhyme like this: My Very Educated Mother Just Served Us Nine Pizzas. To learn more click on the menu below!
