The first successful space probe to explore a planet is Mariner 2, which was launched in August 1962 to fly by Venus. Over time, more space probes were launched, and more information about our solar system was gathered. A notable space probe is Voyager 2, which flew by Jupiter, Saturn, Uranus and Neptune before leaving the Solar System into interstellar space, a place between the stars.= = = Blue's Clues = = =
