By duration · Order from shortest to longest.

1. A qualifying rodeo bull ride 8 sec

   Riders must stay on with one hand for the full count to score at all — touching the bull or themselves with the free hand means instant disqualification.

2. The world's longest scheduled flight, Singapore to New York 19 h

   The route covers about 15,300 km. The aircraft is configured with no economy class at all — partly so passengers survive the experience.

3. One year on Mercury (a full orbit of the Sun) 88 days

   Mercury's spin is so slow that a single sunrise-to-sunrise day there lasts about two of its years — you could outwalk its sunset.

4. A tiger's pregnancy 105 days

   Cubs are born blind and helpless at around a kilogram — yet within two years they're apex predators ten times their mother's litter weight.

5. A full-term human pregnancy 280 days

   Only about 4% of babies arrive on their due date — and the classic count starts from before conception even happens.

6. One orbit of Pluto around the Sun 247.9 years

   Pluto hasn't completed a single orbit since its discovery in 1930 — it won't finish its first 'observed year' until 2178.
