As its 2.8 billion miles from the sun, about 30 times as far as Earth, Neptune gets little sunlight. The average surface temperature is about 200 degrees Celsius. However, it has an internal source of heat, thought to be from radioactive minerals deep in the planet. At Neptunes core, the temperature goes to 7,000 degrees … See more A gas giant and the furthest major planet from the sun, Neptune has been found to have very active weather patterns. Its distance from the sun means the atmospheric temperatures can be some of the lowest in the … See more Hydrogen is the dominant gas in Neptunes atmosphere, with smaller amounts of helium, methane and other hydrocarbons. Its strong gravity lets it retain light gases that escape from smaller planets, like Earth. See more Neptune has the highest measured wind speeds in the solar systemup to 1,200 miles per hour. The large temperature difference between the internal heat source mentioned … See more WebMar 31, 2024 · Neptune is dark, cold, and very windy. It's the last of the planets in our solar system. It's more than 30 times as far from the sun as Earth is. Neptune is very similar to Uranus. It's made of a thick fog of water, ammonia, and methane over an Earth-sized solid center. Its atmosphere is made of hydrogen, helium, and methane.
