Detailed explanation-1: -However, in a very real sense, the Jovian planets are like intermediate objects between the terrestrial planets and the stars. Where are they? The semimajor axis of Jupiter’s orbit is 5.2 astronomical units, that of Saturn 9.5. . The corresponding orbital periods are 11.9 years and 29.5 years.
Detailed explanation-2: -And Neptune makes a complete orbit around the Sun (a year in Neptunian time) in about 165 Earth years (60, 190 Earth days). Sometimes Neptune is even farther from the Sun than dwarf planet Pluto.
Detailed explanation-3: -The period of revolution increases as the distance of the planet increases from the sun. So Neptune has the longest period of revolution.
Detailed explanation-4: -The answer is yes. Jovian planets have longer days than terrestrial planets because their rotation axis is tilted more towards the sun.
Detailed explanation-5: -Mercury: 88 days. Venus: 225 days. Earth: 365 days. Mars: 687 days. Jupiter: 4, 333 days. Saturn: 10, 759 days. Uranus: 30, 687 days. Neptune: 60, 190 days.
