The Earth's period is Earth 1 year Planet (or Dwarf Planet) Distance from the Sun (Astronomical Units Number of miles km) 039 AU, 36 million miles 57.9 million m 0.723 AU 67.2 million miles 108.2 malion km Mercury 0 Earth AU 93 millson aides 149 6milion k 5NAL 141 6millson mals9 mallion km

Explanation / Answer

assuming mass of earth and mars to be same

SQRT(GM/r )= Velocity

period = 2pie*r/velocity

so the period will be in the ratio: r *sqrt(r)

SO TIME PERIOD OF MARS = 1 year *1.524*sqrt(1.524) = 1.8813 years
