There have been a series of robotic probes to every planet in the solar system, and the two Voyager probes are approaching (or perhaps have just passed, we're not yet sure) the "edge" of our solar system. But no human has ever been further away than the Moon.
not yet so far
The furthest man-made object from Earth is space probe Voyager 1,launched 1977.It is,as of May 9,2011,about 17,300,000,000km from the Sun.
The farthest man-made object from Earth is Voyager 1 spacecraft, which was launched by NASA in 1977. It has since traveled beyond our solar system and continues to transmit data back to Earth. Hubble Space Telescope is in low Earth orbit and not as far from Earth as Voyager 1.
It's not clear what you mean by "visited", here. All man-made spacecraft ORIGINATED from Earth. Some of them later RETURNED to Earth as well, and quite a few of them were designed to STUDY Earth (for example, weather satellites).
Not yet so far..:-)because its not possible to a human to go onto a space without any spacecraft... but The first man who jumped in an earth's orbit with a spacecraft is "YURI GAGARIN"
Sputnik 1 was the spacecraft that added an element of competition to US soviet relations when it became the first successful man made earth satellite. It was launched on October 4, 1957.
What nationaility was the first man to orbit the earth in the space craft
A spacecraft is any man made object capable of reaching space. An aircraft is any man made object capable of flight.
Man-made spacecraft can travel at speeds up to about 17,500 miles per hour (28,000 kilometers per hour) in outer space. This speed allows spacecraft to escape Earth's gravitational pull and travel to other planets, moons, and even beyond our solar system.
Sputnik; Competition
The name of the man-made vehicle designed to travel through space is a spacecraft. Examples include the Apollo spacecraft, which carried astronauts to the Moon, and the Space Shuttle, which was used for missions to low Earth orbit. Other notable spacecraft include the International Space Station and various robotic probes like Voyager.
As far as man-made objects go, the Great Wall of China
