Neptune is undoubtedly one of the most beautiful planets in the solar system. That is the only planet in the solar mechanism that to be predicted mathematically before it was directly observed. Lot of what us know around this shining blue planet comes from the data gathered through NASA’s Voyager 2 spacecraft during its Neptune flyby in 1989.

Both Uranus and Neptune belong come the category of ice cream giants. Ice cream giants are various than gas giants (Jupiter and Saturn). Together opposed to gas giants (that contain much more than 90% the hydrogen and also helium), ice giants consists of just 20% that hydrogen and also helium in mass. Ice giants are largely composed of heavier facets like oxygen, carbon, nitrogen and also sulfur.

The upper atmosphere of Neptune is mostly composed that hydrogen and helium, with trace concentration of methane. As you go deeper into the planet, the concentration that compounds favor ammonia, methane, carbon (diamond) and other hydrocarbons increases. You have the right to know much more about the internal of Neptune by watching the video clip below:


At high altitudes, the composition of Uranus and Neptune is an extremely similar. The blue shade of both the ice cream giants have the right to be added to the existence of methane in their upper atmospheres. Methane absorbs most of the red light incident on the planets which makes them show up blue in color. However there is a distinction in the shade of these planets: Uranus has a cyan blue color (blue-green) whereas Neptune has a vivid azure blue shade (bright blue).

Hence, there have to be one more unknown link in Neptune’s environment that is yet to be identified.The factor for the deep blue hue that Neptune is tho a mystery: the really reason why we must put an orbiter roughly Neptune soon.

Several objectives are gift planned to discover Neptune. A mission choose Cassini (that spent 13 year orbiting Saturn) would not only aid us check out the secrets of Neptune yet also help us come learn about the formation and properties of ice cream giants. Follow to a study, distant exoplanets roughly other stars aremore likelyto be ice giants choose Neptune.

Artist principle of Neptune Orbiter (NASA)

Neptune Orbiter is a suggest mission by NASA the would check out Neptune and its moons just like Cassini. Although over there is no official date for that is launch, it would take about 8 come 10 year to with Neptune after the is launched.

Do friend think that is essential for us to launch one orbiter come Neptune soon? allow us recognize your think in the comments.Cover picture Credit: ESA/NASA
