Quick Answer. One year on Neptune is equal to around 165 Earth years or 60,190 Earth days, which is the amount of time it takes the planet to complete its orbit around the sun. Days on Neptune last about 16 hours, which is 8 hours less than Earth. This is the amount of time that it takes for Neptune to make a complete rotation on its axis.
Neptune orbits around the sun every 165 years at an average distance of 2.8 billion miles (4.5 billion km). It spins on its own axis every 16 hours compared to 24 hours on Earth. Due to its far distance from the sun Neptune has an extremely cold outer atmosphere with temperatures averaging around -220C (-364F).Temperatures at its center rise to around 5000C (9000F). Neptune has 13 known satellites, the largest being Triton (picture right) which has a diameter of around 1,681 miles (2,705 km).ue to its far distance from the sun Neptune has an extremely cold outer atmosphere with temperatures averaging around -220C (-364F). Temperatures at its center rise to around 5000C (9000F).
