**Calculating the Mass of the Oort Cloud**

The mass of an average comet's nucleus is about \( 1.0 \times 10^{14} \) kg. If the Oort cloud contains \( 2.0 \times 10^{11} \) comet nuclei, what is the mass of the cloud in units of Earth masses? (Note: Earth's mass is \( 5.97 \times 10^{24} \) kg.)

\[ \text{mass of the Oort cloud} = \underline{\hspace{4cm}} M_{\oplus} \]

**Comparing with Neptune's Mass**

Compare that with Neptune's mass. (Note: Neptune's mass in units of Earth's mass is \( 17.1 \, M_{\oplus} \).)

\[ \frac{\text{mass of the Oort cloud}}{\text{mass of Neptune}} = \underline{\hspace{4cm}} \]
