How Fast Is Parker Solar Probe?

The Parker Solar Probe is the fastest human-made object ever — over 190 km/s, made by skimming within 9 solar radii of the Sun. It uses Venus gravity assists to slowly tighten its orbit, with each pass diving closer to the Sun than any spacecraft before it.

Parker Solar Probe is the first spacecraft named after a living person — solar physicist Eugene Parker, who first predicted the solar wind in 1958.
