If you mean how far has man himself gone, the answer is only as far as the Moon. Unmanned space probes such as the Pioneer and Voyager family, have now reached beyond the solar system. The furthest anything sent by man has reached into space is probably radio waves, which will by now stretch to somewhere around 100 light years (though most of those only went into space 'accidentally', being leakage from terrestrial radio transmissions meant for other people on Earth).

Man

moon

man made machine

some where in between sun and the nearest star

remember those stuff they sent some 20 years ago called voyager 1 and 2

The Voyager 1 spacecraft is an 815-kilogram robotic space probe of the outer solar system and beyond, launched September 5, 1977, and is currently operational. It visited Jupiter and Saturn and was the first probe to provide detailed images of the moons of these planets.

Voyager 1 is the farthest artificial object from Earth, traveling away from both the Earth and the Sun at a relatively faster speed than any other probe. The New Horizons mission to Pluto was launched from Earth at a faster speed than Voyager 1, but since that probe will not get all the gravity assists which sped Voyager along its path, it will never pass Voyager 1.[1]

As of April 4, 2007, Voyager 1 is over 15.18 terameters (15.18×1012 meters, or 15.18×109 km, 101.4 AU, or 9.4 billion miles) from the Sun, and has thus entered the heliosheath, the termination shock region between the solar system and interstellar space, a vast area where the Sun's influence gives way to the other bodies in the galaxy. If Voyager 1 is still functioning when it finally passes the heliopause, scientists will get their first direct measurements of the conditions in the interstellar medium. At this distance, signals from Voyager 1 take more than thirteen hours to reach its control center at the Jet Propulsion Laboratory, a joint project of NASA and Caltech near Pasadena, California. Voyager 1 is on a hyperbolic trajectory and has achieved escape velocity, meaning that its orbit will not return to the inner solar system. Along with Pioneer 10, Pioneer 11, and its sister ship Voyager 2, Voyager 1 is an interstellar probe.

For a man, it is thought Jim Lovell and his Apollo 13 crew have travelled the longest distance from Earth when they took a gravitational slingshot to return home in April 1970.

For a man-made spacecraft, it is about as far as the area we know as the heliosheath, between the heliopause and the termination shock. That spacecraft is Voyager 1

Piloted missions, we have reached the Moon, but satelittes we have launced are as far out as the Oort CXloud, and continuing to move away from the system, into instellar space (between Sol and another star system).

I think those satelittes are Pioneers I and II? Correct me if I am wrong, please someone?

I think that the voyagers reached Pluto.
