A single rotation of Venus takes longer than a year on Venus.
Venus spins once every 243 Earth days but orbits the Sun in 225, so a single rotation outlasts its whole year.

Every claim from this day’s challenge, with its verdict, explanation and sources.
Round 1
Outer space is a vacuum.
It's the best vacuum we know, but not empty: interstellar space still holds gas, dust, radiation, and magnetic fields — roughly one atom per cubic centimeter.
The "five-second rule" prevents bacteria from transferring to dropped food.
Bacterial transfer is almost instantaneous. Moisture and surface type matter far more than time; a wet slice of fruit hits the floor and is immediately contaminated.
Round 2
A woman convinced doctors she was giving birth to rabbits.
Mary Toft's 1726 hoax fooled the King's own surgeons until she confessed to inserting animal parts before examinations.
There is a place on Earth closer to astronauts than to any other human.
Point Nemo, the oceanic pole of inaccessibility, lies 2,688 km from the nearest land — while the ISS passes ~400 km overhead.
Drinking coffee at a young age will stunt your physical growth.
Coffee has zero effect on bone growth or ultimate height. The myth was fabricated by early 20th-century cereal manufacturers competing for the breakfast market share.
Round 3
Mammoths were still alive when the Great Pyramid was finished.
A dwarf mammoth population survived on Wrangel Island until about 2000 BC — some 500 years after the pyramid's completion (~2560 BC).
Saturn would float in water.
Its average density (~0.69 g/cm³) is below water's, but no ocean big enough exists; the statement describes density, not a doable experiment.
Bananas stored together make each other radioactive.
A banana's radioactivity comes from its own potassium-40; neighboring bananas contribute nothing. Buy freely.
