Detailed explanation-1: -One day on Neptune takes about 16 hours (the time it takes for Neptune to rotate or spin once). 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-2: -Neptune is the eight planet in our solar system, at an average distance of 2.8 billion miles from the Sun. Like the other gas giants, its rotation is fast, at about 19 hours. Neptune takes 165 years to make one orbit around the Sun and has 13 known satellites.
Detailed explanation-3: -Neptune takes about 16 hours to rotate once (a Neptunian day), and about 165 Earth years to orbit the sun (a Neptunian year).
Detailed explanation-4: -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-5: -Neptune: 5.43 km/s (12, 146 miles per hour), or a period of about 163.72 years.
