Taking the age of Earth to be about 4 X 10^9 years and assuming its orbital radius of 1.5 X 10^11 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 X 10^42 m
8 X 10^21 m
3 X 10^21 m
4 X 10^21 m
