SECTION 3. Orbital and Rotation Periods of Planets and Satellites out as far as Jupiter.

Here are The Planetary rotation periods, expressed in Earth days. Mercury 58.6462 and Venus 243.0187 and Earth 0.9972697 and Mars 1.02596 and Jupiter 0.41354 (Data source The Planetary Scientist’s Companion, by Lodders and Fegley, Oxford University Press, 1998, pages 87 to 90, Table 2.4) Here is a scan of the relevant data from this above table. Orbital periods are in the “P Orbital (days)” column, and rotation periods are in the (adjacent) “P Rotation (days)” column.

Note:- For satellites, the rotation period is precisely equal to the orbital period, due to “tidal locking”. You can see this by the letter “S” in the rotation periods column – the letter “S” standing for “Same”, ie:- the same as the orbital period.
