To the moon 1969.
200 miles
16000000
Voyager 1 is the furthest and Voyager 2 is the second furthest
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.
Voyager 1 is the furthest man-made object from Earth. It is 10.3 billion miles from the Sun. It takes 15 hours for signals to reach Earth from this distance.
From Cape Canaveral, around the moon, and back to earth. Greatest distance from earth during the trip = about 240,000 miles, or roughly -- 0.0056 of the shortest possible distance to Mars, -- 0.0026 of the distance to the sun, -- 0.00000004 of the distance to the nearest star outside the solar system.
The furthest man-made satellite from Earth is Voyager 1 - launched on the 5th of September 1977.
No human beings have ever been to Neptune (as far as we know).
No. The furthest "man" has gone is the moon.
No one has every been to Mercury. The furthest man has been is to the Moon. Probes have been sent to Mercury
It is possible for something to be so far away from the Sun that that thing and the Sun would not be aware of each others existence. But for a human being the furthest man can get from the Sun at the moment is to be on the ISS when it is on the dark side of the Earth at Aphelion. However, the astronauts on the Moon at Aphelion and Apogee would have been the furthest man has travelled (If that possibility existed because of the positions of the orbits)
The furthest Man has gone, is to the Moon. No Man could even land on Saturn as it does not have a surface.
