Explanation:

Step1: Read data for Earth - Sun distance

From the table, Earth's distance from the Sun is $149.6\times10^{6}$ km.

Step2: Read data for Jupiter's revolution period

From the table, Jupiter takes 12 years to revolve around the Sun.

Step3: Find planet with rings and less gravity than Saturn

From the table, Uranus has rings and its gravity ($8.7$ m/sec²) is less than Saturn's ($10.0$ m/sec²).

Step4: Read data for Venus' rotation period

From the table, a day on Venus (rotation period) is 243 days.

Step5: Determine farthest - apart planets

The planets farthest apart are Neptune and Mercury as Neptune is the farthest from the Sun and Mercury is the closest.

Step6: Find planet with shortest orbit

From the table, Mercury has the shortest time to revolve around the Sun (88 days), so it has the shortest orbit.

Step7: Calculate mass difference between Jupiter and Saturn

Jupiter's mass is $18980\times10^{23}$ kg and Saturn's is $5680\times10^{23}$ kg. The difference is $(18980 - 5680)\times10^{23}=13300\times10^{23}$ kg.

Step8: Find planet with third - greatest gravity

Sorting the gravities: $23.1$ (Jupiter), $11.0$ (Neptune), $10.0$ (Saturn), $9.8$ (Earth), $8.9$ (Venus), $8.7$ (Uranus), $3.7$ (Mercury and Mars). The third - greatest gravity is Earth's ($9.8$ m/sec²).

Step9: Find planets with same gravity

Mercury and Mars both have a gravity of $3.7$ m/sec².

Step10: Calculate number of moons of Uranus and Neptune

Uranus has 27 moons and Neptune has 14 moons. The total is $27 + 14=41$ moons.
