Neptune is the eighth and the last planet in our solar system. It has eight moons and the biggest of the moons is called Triton. The distance from the Sun to Neptune is 2,798,000,000 miles (4,503,000,000 km). The distance between the Earth and Neptune is approximately 4.4 billion km away. Neptune's blue color is the result of a gas called "methane" in its atmosphere. Neptune's atmosphere is mainly Hydrogen (around 80%), Helium (around 19%) and Methane (around 1%). The temperature of Neptune can go down to 55 Kelvin or -218 degrees Celsius. Neptune consists of (molten) rock and metal, bounded by a blend of rock, water, ammonia, and methane. One year on Neptune would be 164.79 earth years for us, or 60,190 days. One day on Neptune would be 16 hours, 6 minutes and 36 seconds. The only problem is that Neptune isn't a single solid object like the terrestrial planets, so different parts of the planet rotate at different speeds. The gravitational pull on Earth and the gravitational pull on Neptune are very similar. The difference between the weights is about 15 pounds and on Neptune you would weigh more.
