Dark, cold & whipped by supersonic winds, Neptune is a hydrogen & helium gas giant in our solar system. Over 30 times as far from the sun as Earth, it takes almost 165 Earth years to orbit our sun. On Neptune, one "day" (time it takes to rotate once on its axis) takes 16 hours. It has 13 moons & 6 rings.
These four images, taken a few hours apart with the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3, show Neptune, the eighth and outermost planet of the Solar System. Hubble’s images were taken to celebrate the first complete orbit of the planet since its discovery in 1846. The four images show different faces of the planet as it rotates on its axis.
