Both Voyager 1 and 2 have travelled through the solar system, I believe Voyager 1 is the only one which has left the solar system (or is in the process of).
Voyager I and II are pretty much on the edge of solar system.
Voyagerhttp://en.wikipedia.org/wiki/Voyager_1 1
The Voyager 1 spacecraft is a 722-kilogram (1,592 lb) space probe launched by NASA on September 5, 1977, to study the outer Solar System and eventually interstellar space. Operating for 33 years, 11 months and 12 days as of today (17 August 2011), the spacecraft receives routine commands and transmits data back to the Deep Space Network. It will be the first probe to leave the Solar System and is the farthest man made object from Earth.The two Voyager satellites have left the solar system and passed the "heliopause", the boundary layer between the solar system and deep space.V1 Launch Date: 1977-09-05 12:56:00 UTCV2 Launch Date: 1977-08-20 14:29:00 UTC
The outer planets in our solar system have many moons orbiting around them. They also have rings, with Saturn being the most well-known for its extensive ring system. Additionally, the outer planets have a variety of spacecraft that have been sent to study them, such as the Galileo spacecraft for Jupiter and the Cassini spacecraft for Saturn.
The two Voyager space probes are robotic spacecraft launched in 1977 as the first spacecraft to examine the outer planets. Both are still operating, having passed the orbits of the outer planets, and drifting toward the boundary of the solar system.
You can go to many planets
The Voyager spacecraft does not have shuttles. It is a pair of robotic spacecraft launched by NASA in 1977 to study the outer Solar System. Each Voyager spacecraft is equipped with scientific instruments to study planets and their moons but does not have shuttles for transportation.
Outer space is much bigger than the solar system.
The outer (major) planets of our solar system are the 4 gas giants:JupiterSaturnUranusNeptuneFurthermore, 4 out of the 5 dwarf planets are also in the outer solar system, beyond the orbit of neptune:PlutoHaumeaMakemakeEris
because they are far away from our solar system
B. The young sun's solar winds pushed gases outward to the outer solar system.
