Solution:

To find absolute zero in Fahrenheit, we use the relationship between Celsius and Fahrenheit:

\[
F = \frac{9}{5}C + 32
\]

Absolute zero in Celsius is \(-273.15^\circ C\). Substitute this into the formula:

\[
F = \frac{9}{5}(-273.15) + 32
\]
\[
F = -491.67 + 32 = -459.67
\]

Rounding to the nearest whole number, we get \(-460^\circ F\).
