Description
Neptune. Artwork of the gas giant planet Neptune showing clouds and its thin ring system (running from upper left to lower right). Neptune mainly comprises gaseous hydrogen and helium, with small amounts of methane. It has a diameter of around 50,000 kilometres, almost four times that of the Earth. It orbits the Sun at a distance of 4500 million kilometres, taking almost 165 years for each orbit. Its blue colour is due to methane in its upper atmosphere. The Great Dark Spot (centre left) is thought to be a large storm system, and it has numerous white, high-altitude clouds associated with it.
