Neptune's core which is approximately the size of Earth is believed to be composed of rock and Ice the course covered with a thick mantle that contains water liquid ammonia and methane mixed with gases it is bitterly cold on Neptune with an average temperature of -210 degrees Celsius however it is warmer than expected for a planet's distance from the Sun since Neptune has an internal energy source like others Neptune is the fourth largest planet in terms of diameter making it the smallest and gas giants average distance from the center of the planet to the surface is 15299 Miles but like most spending bodies the rotation causes it to fold in the center or equator radius of the poles is 15125 Miles slightly smaller than the equator …show more content…
Neptune's average day last up to 16 hours six minutes and thirty-six seconds because Neptune isn't a solid body some parts of it were that much faster or slower than others for example the equator takes 18 hours to orbit the whole planet average is 16.1 hours and yet again the polar regions beat the average by 4 hours at these regions the orbit is just 12 hours the average year on Neptune take 60198 days the atmosphere of Neptune contains gas gaseous hydrogen helium methane ethane that's fine ammonia and water vapor the methane absorbs red light giving the planet it's blue color the atmospheric pressure of a liquid surface is a hundred thousand times greater than it is on Earth.Neptune has the wildest and strongest weather in the solar system its atmosphere has dark spots which can come and go and it is the windiest planet in the solar system average temperatures equal -112 degrees Celsius because it's so far away from the sun doesn't receive as much solar energy many people discovered Neptune and all of them found it in different ways mathematician Alex Brevard astronomers John couch from Britain and her band Live we are from France and lastly astronomer Observer Zone Godfrey GAO German they all managed to predict and find Neptune the planet was named after the Roman God of oceans mostly because it's blue color we are already being able to discover parts of Neptune through the Voyager Neptune actually has 13
