What Does Neptune Look Like? Neptune has a Great Dark Spot, it is darker than the blue colors on the outside. It has streamers of white clouds that change in appearance every few hours, the clouds consist of crystals of methane-ice. The two dark storm spots resemble Jupiter’s Great Red Spot, it’s a huge tropical storm big enough to swallow our entire planet Earth. Planets with gases all have rings. Neptune’s ring has two brighter rings at the outside and the fainter one at the inside.

What is Neptune made of? The inner two thirds of Neptune is a mixture of molten rock, water, liquid ammonia, and methane. The outer third is made of a heated gas mixture of hydrogen, helium, ammonia, water, and a small amount methane. The methane makes the planet Neptune blue. Neptune is like Jupiter and other big planets who are mostly made of gases.
How does Neptune Compare to Earth? Neptune and Earth are not similar. The blue planet Neptune takes 165 years to orbit the Sun. Earth only takes one year to rotate around the sun. The planet Neptune is almost 2.8 billion miles from the sun. Earth is around 93 million miles from the sun. The Earth rotates once in twenty-four hours, while Neptune rotates once in 16 hours.

Fun Facts The clouds around Neptune’s northern hemisphere are casting dark shadows on the blue cloud deck thirty five miles below. Neptune’s magnetic north and south poles are fifty degrees away from it’s geographic poles, While Earth’s only 10 degrees apart.
Does Neptune have a Moon? In the past the scientists believed Neptune had two moons. The asteroid called Nereid might have been pulled by Neptune’s gravitational field and become a moon. Triton is bigger than Nereid and almost as big as Earth’s moon. When measured against other objects in the Solar System, Triton was the coldest. Some scientists think the streaks were made by eruption of the unreactive gas, nitrogen. Scientists think Triton resurfaced by erupting volcanoes gushing slushy ice squeezed out inside of the core. When the slush was frozen solid, it left the surface on the moon. Huge X’s and huge Y‘s across Triton’s surface did this. Slushy water ice and ammonia ice appeared to have forced their way upward into some of the cracks, forming central ridges and sometimes overflowing onto the surrounding land. The remains of volcanic activity prove that Triton’s surface was hot before. Triton was pulled by Neptune’s gravitational pull like Nereid. A space scientist called it frozen imprint in the earlier times. Voyager 2 took a picture of six moons circling around Neptune, which was given temporary names. They have not given them names yet, but will
