# What is the mass of Jupiter?

Relevance

"Jupiter." The World Book. Millenium 2000. Chicago: World book Inc. 2000. "Its [Jupiters] mass is 318 times larger than that of earth" 1.9 × 1027 kg

Hope this helps!

• Let’s work it out – the art of estimating

Jupiter is about 140,000 kms diameter.

That is 1.4 x 10^5

So, if it was a cube shape, it’s volume would be:

(1.4 x 10^5) x (1.4 x 10^5) x (1.4 x 10^5) cubic kms

= 2.75 x 10^15 (or 2.75 quadrillion cubic kms)

Now for estimating, a sphere is just about half the volume of the cube it fits into, so:

Volume of Jupiter = approx 1.4 x 10^15 cu kms

Need to turn that into cubic metres.

1 cu km = 1 billion cu m (1000 x 1000 x 1000 = 10^9)

So, volume of Jupiter = 1.4 x 10^24 cu m

Now 1 cu m of water weighs 1 tonne, and the specific gravity of Jupiter is about 1.4 because it is a Gas giant (and the gas is under intense pressure). So, Jupiter is about 1.4 as heavy as if it was all water.

Therefore, mass of Jupiter = 1.4 x 1.4 x 10^24 tonnes.

That is about 1.9 x 10^24 tonnes

Or 1.9 x 10^27 Kgs

I bet nobody else will show you how to do this.

By the way, in tonnes it is 1.9 trillion trillion tonnes. I'm not sure what that weird figure someone has published above from their science book - people have no concept of the scale of things.

• 1.899×10^27 kg

Source(s): I weighed it.
• 2,530,274 its 318 larger than that of earths

Source(s): i checked my science book. ;)
• why would you want to know that? I'm sure you could find that in google...
