Neptune cannot be seen from Earth by the naked eye because it's about 3 billion kilometers away. It actually took mathematical studies to find it as a result of a hiccup in the orbit of Uranus. It was named after the Roman God of the Sea for two reasons; one because of its soft blue color, and because this ancient God did not have a dedicated planet. Planet Neptune is the last of the four gas giants, and considered by some as Sister planet to Uranus. They are extremely similar in size, color, and atmosphere.

Neptune's mass is about the size of 60 Earths combined. Because it is so far away, its orbit of the Sun takes about 165 years. One day on Neptune is the equivalent of about 16 Earth hours. Not that anything could ever sustain the 2,000 plus kilometer winds it commands in some areas. Even though its winds travel against its rotational direction, it wins the award for the planet with the most powerful winds. It has several stormy spots, but its most menacing is its Great Dark Spot, about the size of Earth.

Neptune's atmosphere appears to be complimented by misty white methane clouds, which speed along about 50 kilometers above its surface. Planet Neptune projects nearly three times the heat it receives from the Sun. Its core energy creates and controls the planets weather patterns. It also has its own set of four very fine rings, most likely made from the dusty remains of meteors after they collided with one of its eight moons.

One of its moons 'Triton' is the coldest body we know of in the Solar System. It travels its orbit of Neptune in the opposite way of the planets rotation. Only two moons in the Solar System orbit their planets this way. Neptune's other large moon Nereid orbits in the same way as the planet, so these two moons actually pass each when orbiting their home planet. Six other smaller moons orbit Neptune. Their orbits takes place between Neptune's biggest satellite, 'Triton', and the planet itself.

Triton also has some unusual planetary activity which is still not fully understood. It blows a unique fall out upwards to about 8 kilometers, before the winds takes control, and races them along the atmosphere for more than 140 kilometers. We can only guess that they are made from fine dust particles, but even that suggests they should be scattered away given the influence of such high planetary winds.
