Is there advantage of measuring stellar parallaxes from Mars rather than from Earth? Would it be more accurate than from Earth?

Thanks

Think about how parallax distances are measured. What would make them more accurate? What might the difference between the Earth and Mars be in relation to this? (Hint: parallax measurements require two observations six months apart).

Ok i got it. It's because the distance from mars to the sun is greater than from the sun to earth, creating a larger baseline.
