Weight of Space & Nature: From Lightest to Heaviest
Masses of planets, the Sun and the Moon from NASA's Planetary Fact Sheet, plus scientific estimates for clouds and comets — always labeled as estimates where they are.
2/8
Using a log scale so small objects stay visible — the numbers stay real.
- the Sun1.99 × 10^30 kg
total mass of the Sun as listed in the NASA/NSSDCA Sun Fact Sheet (1,988,400 x 10^24 kg, about 332,900 times Earth's mass)
- a cumulus cloud500,000 kg
order-of-magnitude estimate: a 1 cubic kilometre cumulus cloud at about 0.5 g of droplets per cubic metre
