It's not the fastest anymore! That manhole cover topped out at around 55 km/s, while the Parker solar probe achieves up to 700 km/s at the point in its orbit closest to the Sun. Also, depending on how you define "object" the clumps of particles we assemble and shoot around the ring in the Large Hadron Collider at 0.99c are much faster than both.
