How much does Jupiter weigh (kg)?

Answer

Jupiter weighs :
1 899 000 000 000 000 000 000 000 000 kilograms
That’s about a thousand times less than the sun:
1 989 000 000 000 000 000 000 000 000 000 kilograms
but about 300 times more than the earth :
5 974 000 000 000 000 000 000 000 kilograms

Because such large numbers are not convenient to work with, masses of planets are usually expressed in Earth mass, or in Jupiter mass. A planet of 3.2 Earth mass is therefore a planet that is 3.2 times heavier than Earth. A planet of 1.2 Jupiter masses is 1.2 times as massive as Jupiter.
