What is the fastest man made object ever recorded?

Speeed of Light :

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph

As an object approaches the speed of light, its mass rises precipitously. If an object tries to travel 186,000 miles per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light

Fastest man-made object ever :

The Parker Solar Probe just earned the title of the fastest-moving manmade object. Launched by NASA this past August 2018, this robotic spacecraft is currently very, very near the Sun, on its way to probe the outer corona of our local star.

The Parker Solar Probe is a NASA robotic spacecraft launched in 2018 with the mission of making observations of the outer corona of the Sun. It will approach to within 9.86 solar radii from the center of the Sun, and by 2025 will travel, at closest approach, as fast as 690,000 km/h, or 0.064% the speed of light

How fast is it going?

According to NASA, its current speed is 153,545 mph (or 68.6 kilometers per second). But really, that just means super fast. It's nearly impossible to imagine something that fast when the fastest man-made stuff on Earth is perhaps a rail gun projectile at about 2.52 km/s. That means the Parker Solar Probe is traveling at a speed that is 27 times faster that the fastest thing we've got down here. Zoom fast.You will probably see something about the speed of the Parker Solar Probe labeled as the heliocentric velocity. What's the deal with that?

On Earth, this is rarely an issue. If you are driving your car at 55 mph, everyone understands that we are measuring this velocity with respect to the stationary ground. In fact, velocities only really make sense when measured relative to some reference frame. On the Earth, the obvious reference frame is the ground.

Parker Solar Probe Prepares for Third Venus Flyby:

Early on July 11, 2020 (UTC), the spacecraft will perform its first outbound flyby of Venus, passing approximately 516 miles above the surface as it curves around the planet. Such Venus gravity assists play an integral role in the Parker Solar Probe mission. The spacecraft relies on the planet to rid itself of orbital energy, which in turn allows it to travel ever closer to the Sun after each Venus flyby. The mission’s previous two Venus flybys swooped past the Sun-facing side of the planet, and this will be Parker Solar Probe’s first pass on Venus’ night side.
