For the fastest manmade object: 6759 years


The edge of our solar system is where our suns gravity stops being the greatest gravity affecting us. This boundry is about 100 000AU (astronomical unit) or about 9 300 000 000 000 miles. The fastest man-made object we have launched into space is Helios 2 with a speed of 157078 mph. So the time it would take for Helios 2 to reach the edge of our solarsystem is about 59206254,2176 hours or roughly 6759 years.
