One of the moons of Jupiter, Europa, has shown evidence of water plumes coming from its surface. Europa is $${{ params.r_sun_europa }} \times 10^{11}$$ $$\rm{m}$$ from the sun, while Earth is $${{ params.r_sun_earth }} \times 10^{11}$$ $$\rm{m}$$ from the sun.

## Part 1#

Compare the intensity of solar radiation reaching the Earth $$I\_{Earth}$$ to the solar radiation reaching Europa $$I\_{Europa}$$.

$$\frac{I\_{Earth}}{I\_{Europa}} =$$
