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. In 2011, Neptune completed its first orbit since its discovery in 1846. On Neptune, one "day" (time it takes to rotate once on its axis) takes 16 hours. It makes a complete orbit @ the sun in 165 Earth years. It has 13 moons & 6 rings. Photo: the "sideways" planet with vertically orbiting rings <3
In 1989, Voyager 2 made our first close encounter with the stunning blue planet Neptune. Its surprisingly turbulent, storm-laden atmosphere, this far from the sun, was clearly being driven by heat from deep within the planet
This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach.
How far is Neptune from Earth? The distance from one planet to another is constantly shifting because both bodies are moving through space. When Neptune and Earth line up on the same side of the sun, at their closest, they are only 2.7 billion miles (4.3 billon kilometers) apart. But when the planets are on opposite sides of the sun, they can put as many as 2.9 billion miles (4.7 billion km) between them.
