The length of Earth's orbit is: .C .= .2π(93,000,000) .≈ .584,336,234 miles
Hence, the Earth travels 584,336,234 miles in one year.

| Ok, Stuck686, before you go, that's different from what Jhevon got, notice that my answer had pi in it, it is the same when you work it out. that being said, notice that several of my answers have pi in them, that's because i wanted to cut down on rounding of decimals, so the answer is more exact |
