The Mass of Jupiter

We can estimate the mass of Jupiter from the period and size of an object orbiting it. For example, we can use Jupiter's moon Callisto to estimate it's mass.

Callisto's period: $p_{c}=16.7 days$

Callisto's orbit radius: $r_{c}=1,900,000 km$

Now, using Kepler's Law we can work out the mass of Jupiter.

:label: eq1
m_{j} \approx \frac{r_{c}}{p_{c}} \times 7.9 \times 10^{10}

:label: eq2
m_{j} \approx 1.9 \times 10^{27} kg

Jupiter is 11.0x larger than Earth!

NASA provides a lot more information about the physical characteristics of Jupiter [here](https://solarsystem.nasa.gov/planets/jupiter/by-the-numbers/).

There might even be more planets out there with a similar mass to Jupiter {cite}mayor1995jupiter,guillot1999interiors!
