As far as we know, no human being has ever been farther from Earth than the moon.
All space probes to any other planet have been unmanned.
Space probes are automatic and are programmed to send scientific data such as images and readings back to Earth.
The human race currently do not have the technology for man to survive long periods of space flight. Space shuttles have enough problems getting into our own orbit, let alone further than our own orbit. It would take years to reach Neptune.
