What are the differences in rotation between inner and outer planets?
The planets rotate at a speed that is typically dependent upon mass, however this is not always the case. Venus rotates only once in 284 days, and does so in a retrograde (backward) fashion as compared to all the other planets. Neptune rotates once each 16 hours (equatorally), Saturn 10 hours 14 minutes, Jupiter in just under 10 hours, while Mars rotates once in 24 hours and 39 minutes, and Mercury experiences one revolution on it’s axis every 58.7 earth days. The other difference between the planets is the angle of alignment to the solar plane, or ecliptic. Earth is tilted at about 23 degrees, while Jupiter is only tilted 3.13 degress, but Uranus is tiltes 97.77 degrees! So we have planets that rotate backward, travel around the sun on their side, and have days that are only 10 hours long. There is an elborate theory called relativity which attempts to explain bodies in motion through the use of gravitation, which is described as a “warp” in the space/time continuum. Actually, gravita
