When considering the period of rotation of the Earth’s orbit around the Sun, if the mass of the Earth was doubled but the radius of its orbit was kept constant how would this affect the period of rotation of the Earth around its orbit?

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
