I thought it was Deep Space 1
using an ion drive, but
apparently it only went 10,000mph at it's peek speed (relative to earth). For some reason, and I probably should blame some TV special I'd watched
on discovery or space, that it was stated that the ion drive would achieve the fastest speed ever by an object made by man. (Which is probably likely,
but I guess it hasn't achieved that yet.
The Pioneer 10
space craft achieved 32,400 mph for it's flight to
jupiter, and then using Jupiter's gravity it sped up to 82,000 mph for it's flight out of the solar system. A few sites credit it as the fastest man
made object, but because the question is interesting I'll probably look deeper into this.
Pioneer 10's speed relative to the Sun is 27,380 mph (12.24 km/sec). As a nifty peice of trivia: Pioneer 10 is heading away from our Sun generally
in the direction of the red star Aldeberan. That's the main star seen as the eye of The Bull in the constellation Taurus in Earth's night sky.
Aldebaran is about 68 light years away. Pioneer 10 should arrive at Aldeberan in 2 million years.
But then there's Galileo
Probe's approach to Jupiter in 1995, "The Probe was the fastest man-made
object ever. Decelerating from 106,000 to 250 mph in four minutes..." seems to be the fastest man made object ever.
So much info out there, so little time here.
