 * Like Jupiter, Saturn and Uranus, Neptune is a giant gas plant with an atmosphere consisting of hydrogen, helium and methane. It's slightly smaller then Uranus, with a diameter of 49 500 km, but has the same rotation rate. Neptune's most striking feature is the great dark spot in the atmosphere. this is very similar to the great red spot on Jupiter.**
 * Neptune is the eighth furthest planet form the sun in our solar system. Neptune was named after the roman god of the sea. It is the fourth largest planet by diameter and is also the third largest in mass.The first two thirds of Neptune is mostly molten rock, water, liquid ammonia and methane.The other third is a mixture of heated gasses contained of hydrogen,helium,water,and methane.That methane is what gives Neptune the blue cloud colour that you see.**


 * Neptune's surface temperature averages 220c but the temperature on the surface of it's largest moon, Triton, is the coldest ever recorded in the solar system.Neptune has 13 moons orbiting around Neptune.**
 * Neptune is 17 times bigger the Earth.Neptune orbits the sun at a distance of 30.1, approximately 30 times going back and fourth from the Earth and the Sun.**
