Question
Taking the age of Earth to be about $4\times 10^{9}$ years and assuming its orbital radius of $1.5 \times 10^{11} \textrm{ m}$ has not changed and is circular, calculate the approximate total distance Earth has traveled since its birth (in a frame of reference stationary with respect to the Sun).
$4\times 10^{21} \textrm{ m}$
