What is the fastest any man made object has traveled. I'm not sure but it's either a spaceship that can go to the moon or a sattelite. Whatever it is what is it's speed in mph or kph? Oh and tell me what it is that can go so fast.

While Voyager is fast, here is some imformation on Helios I and Helios II
The Helios deep space probes were launched in the mid 1970s by the Federal Republic of Germany and NASA, using US Air Force launch vehicles.
There were two in the series, Helios I and Helios II. They were launched to orbit and measure the Sun. They set a speed record for spacecraft at 252,792 km/h (70.2 km/s). They also set the record for closest approach to the Sun, at about 45 million kilometres, slightly inside the orbit of Mercury. The Helios 2 was sent into orbit 3 months after the launch of the Helios 1. Both probes orbited around the sun in an ellipse, with their farthest distance from the sun being almost 1 AU (Astronomical Unit - the distance from the Earth to the Sun) and their closest distance to the Sun at 0.3 AU. The Helios space probes completed their primary missions by the early 1980's, but they continued to send data up to 1985. Presently, these probes are no longer functional, but they still remain in their elliptical orbit around the sun.

I believe the New Horizon's space craft is the fastest yet. Right now, after passing by Jupiter and getting a gravity assist from the giant planet, it is traveling 47,000 mph.

the cheetah is the quickest land animal interior the international however the quickest animal on the entire planet is the peregrine falcon because of the fact they might attain a velocity of over 250mph while diving yet they're slow flyers while flying in a immediately line, the 2d quickest is the prairie falcon because of the fact there almost an identical velocity as peregrine falcons while diving

Voyager I, a space probe launched by NASA in 1977: velocity approx 38,400 mph (relative to the sun).
