Quick Scoop
There’s a bit of trivia here: a nuclear-test manhole cover is often mentioned in speed legends, but the best-supported current record holder is the Parker Solar Probe.
Why it wins
- It was accelerated by repeated Venus flybys and a close pass near the Sun.
- Its record speed was reported on September 21, 2023.
- It is the fastest human-made object currently known in flight.
Tiny context
If you want the “fastest ever claimed” story, the manhole-cover legend is famous, but it is not accepted as the official record.
