How far does Earth travel in one year as it makes one complete orbit?

Although the orbit of Earth around the sun is elliptical, it closely resembles a circle. The orbit can be modeled by #x2 + y2 = 8649#, where the Sun is at the origin and each unit of the coordinate plane represents 1 million miles.

Distance traveled by Earth around the Sun in 1 orbit year: Distance traveled = year in seconds X orbital velocity = (365.256 X 24 X 60 X 60 sec) X 29.78 km/sec) = 9.398 E+08 km, nearly


Answer is rounded to four significant digits (sd). Use 6 sd in orbital velocity for more sd in the answer. Interestingly, you and I also travel nearly this distance around the Sun in one year.
