Mars has an orbital period of very approximately twice that of the earth
Actually, the answer is Mars. Mars' revolution is 1.88 years which is almost twice as the revolution of Earth.
Saturn has a period of revolution that is approximately twice as long as Earth's. While Earth takes about 365 days to complete one revolution around the Sun, Saturn takes roughly 29.5 Earth years to complete its orbit.

Mercury takes 88 Earth days to go around the Sun, but strangely, its day is twice as long taking 176 Earth days to rotate just once! Mercury's slow spin is evidence of why the planet has a magnetic field just 1% as strong as Earth's. (This may have been a very long answer)
