What planets have been visited by spacecrafts?
There have been journeys to the inner planets: the Messenger, Magellan and Mariner spacecraft to Mercury and Venus. There have, too, been expeditions to Jupiter and Saturn and their colorful flocks of moons. Asteroids and comets and the sun itself have also been studied up close. Many of the missions are ongoing.
Has any planet been visited?
When I was growing up, there were nine planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
