By weight · Order from lightest to heaviest.

1. An adult male grizzly bear 270 kg

   Before hibernation a grizzly can pack on more than a kilogram of fat per day, entering the den far heavier than in spring.

2. A Holstein dairy cow 680 kg

   A productive dairy cow gives about 30 liters of milk a day — and burps enough methane to matter in climate accounting.

3. The International Space Station 420 t

   Assembled over 42 flights, it circles Earth 16 times a day at 28,000 km/h, so its crew sees 16 sunrises daily.

   It displaces more than some WWII aircraft carriers and can stay underwater for months, limited mainly by the food supply.

5. A Nimitz-class aircraft carrier 100K t

   A floating city of about 5,000 people, it can sail more than 20 years between refuelings of its nuclear reactors.
