Detailed explanation-2: -Since it is the farthest planet from the Sun it has the longest orbital duration, completing a trip around the Sun in about 165 years. However, one sidereal rotation or day on Neptune is completed in 16.11 hours.
Detailed explanation-3: -Orbit and Rotation And Neptune makes a complete orbit around the Sun (a year in Neptunian time) in about 165 Earth years (60, 190 Earth days).
Detailed explanation-4: -The same is true for the planets around the Sun. Mercury takes approximately 88 days to orbit the Sun completely; Venus: 225; Earth: 365; Mars: 1, 9 years; Jupiter: 11, 9; Saturn: 29, 5; Uranus:84; Neptune: 165 and Pluto 248.
