Uranus and its sister Neptune, share the outer world of the solar system, a light sapphire, 3 billion miles away from the sun.Due to the demotion of Pluto, Neptune is the outer planets.Neptune's name from the Roman god of the sea.Neptune, 2.68 billion miles (4.3 billion kilometers) from earth, about 30000 miles in diameter, is four times the diameter of the earth.Neptune in 165, a year is equal to the earth, there are 16.1 hours a day.If you are in the earth weighs 150 pounds, more than 169 pounds in Neptune.
with all the outer planets, Neptune's rotation is much faster than the earth, so that the rapid rotation of turbulent wind.In fact, in our solar system, all the records of the planet, the fastest winds to Neptune.Neptune's wind sometimes can reach more than 1000 miles per hour, the upper atmosphere with an average of 750 MPH, the wind we don't know why, it is still a mystery.
let scientists were puzzled, why the wind is strong than other exoplanets Neptune?Faster than Jupiter's great red spot hurricane 2-3 times.
the jet propulsion laboratory researchers, mike m and driving force of the research on other planets affect climate, the mysterious winds on Neptune aroused his interest.Formation is the key element of a wind heat energy, heated air on the earth, the sun provides the heat energy, but in the wind of Neptune, and the distance from the sun than the earth far 30 times, get and only 1/900 of the earth, solar energy, this energy is obviously not enough to produce winds of Neptune.Scientists believe that Neptune from another part of energy within their synchronization.
2 spacecraft data test shows that Neptune released from its own internal energy is twice the solar gain, Neptune heat release and heat absorption rate is the highest of all the planets in the solar system.Neptune's internal heat more, its internal heat comes from the radioactive decay of internal material and other chemical processes, the decay will release a lot of heat and chemical process.
but why Neptune can produce so much energy?It is still a mystery.There's been speculation that Neptune is still in the growth state, invagination of gas compressed by gravity will release heat energy.
inner heat source can also explain Neptune gases in the atmosphere of the convection, the convection formed the charming moire.In the atmosphere, there are many bright, white, light and shade of different surface area set in Neptune, so we rely on the brightness of the cloud can distinguish between different latitude.
scientists believe that the style of the cloud is associated with the composition of the sea king nebula, they may be composed of methane, the planet's surface action quickly.Neptune, the movement of the upper hand, is different from we know anything.Neptune on huge storm system that is dwarfed by the storms on earth.
in 1989, the spacecraft take shocked the industry in the next picture 2 scientists, Neptune has a huge storm, in the southern hemisphere have a huge black spot extends 8000 miles wide and big enough to put the planet in the dark spots center, the storm is similar to Jupiter's great red spot, infamous great red spot is a huge anticyclone, it is composed of many smaller storms, maintain, or it will disappear to disperse.
and the big black spot on Neptune, scientists believe that the atmosphere would be rather unrest, storm into the atmosphere, make air rolling back and forth.In the first time that big black spot after 5 years, scientists have found another shocking.The Hubble telescope to Neptune, it found that the largest storm disappeared on Neptune!
Neptune's big dark spots? What happened?Five years' time, the planet's largest storm from the southern hemisphere so easily disappear, but this does not mean, Neptune on all the storm stopped.Astronomers using the Hubble space telescope observations to a new big spots appeared, but this time, dark spots appear on the planet's northern hemisphere, seems to have been in the big patches on Neptune storm system is always in a hurry, don't like Jupiter's great red spot can be lasted hundreds of years.
these storm systems not only briefly, and funny.The scientists found that the size of the big black shock drift for thousands of square miles, and it only happen within eight days.Disappear, reappear, completely singular movement makes the Neptune storm system become one of the most unpredictable storms in the solar system.
