It takes 2.89 earth months.
88 days
Mercury takes about 88 Earth days, or roughly 3 Earth months, to complete one orbit around the Sun.
there are many such planets 1.mercury 2jupiter etc
The travel time to both Mercury and Saturn from the Earth depends so much on the orbit chosen that it is not possible to say how much one is different from the other, or even if one is shorter than the other, until the orbits and accelerations are determined.
It takes Mercury about 3 of our months to orbit the Sun.
8 months
To travel by land in wagon trains, it took two months.
