      Rotation and Revolution of Mercury Like Earth’s Moon (tidally locked to revolution around Earth), Mercury’s rotation has been altered by the Sun’s tidal forces, but it has not locked into a 1:1 spin-orbit resonance. It is in a 3:2 resonance. Revolution period = 3/2 times rotation period. Revolution: ≈ 88 days, Rotation: ≈ 59 days

      receives about 44% less solar energy than Earth. • Mars is about one-half the size of Earth. • Gravity on Mars is about one-third of Earth, so you would weigh about 1/3 as much. • A Mars day (called a sol) is 24 hours, 37 minutes long. A Mars year is 687 Earth days (about 2 Earth years). • Mars surface can be divided into two hemispheres.

Finally, liquid water is almost certainly neces-sary for the origin of life; if we believe that life began shortly after the forma-tion of Earth (16), liquid water must have been present for most of the period between 3.5 and 4.5 aeons ago. Thus, even using our most conservative value of AL, we find a serious discrepancy
