Om Neptune

Neptune is a world of supersonic winds and deep blue mysteries. As the most distant planet from the Sun, Neptune takes 165 Earth years to complete one orbit. Despite receiving only one-thousandth of the sunlight that Earth gets, Neptune radiates 2.6 times more energy than it receives from the Sun. The planet hosts the fastest winds in the solar system, reaching speeds of up to 1,200 mph (2,000 km/h). Its deep blue color comes from methane in its atmosphere, which absorbs red light and reflects blue wavelengths back to space.
