By weight · Order from lightest to heaviest.

1. An average newborn human baby 3.4 kg

   Newborns arrive with about 300 bones; many fuse over the years down to the adult count of 206.

2. The Liberty Bell 943 kg

   Its famous crack was widened on purpose — an 1846 repair meant to stop the fracture instead ruined the bell's tone for good.

3. A Space Shuttle orbiter, empty on the runway 78 t

   Returning from orbit, the shuttle was a glider with no engines for a second try — every landing had to work the first time.

4. A SpaceX Falcon 9 rocket, fully fueled on the launch pad 549 t

   More than 95% of that is propellant; the reusable first-stage booster lands weighing almost nothing by comparison.

5. The Eiffel Tower 10.1K t

   The iron grows in summer: heat expands the sun-facing side, leaning the top away from the sun and adding around 15 cm of height.

6. The Burj Khalifa in Dubai 500K t

   The world's tallest building is tall enough to watch the sunset at the base, ride the elevator up, and watch it set again.
