Neptune; Icy And Interesting Essay

964 words - 4 pages

Neptune is the eighth planet from the sun, the third largest by mass, and the forth largest in diameter, at 49,532 km. Among the gaseous planets Neptune is the most dense, its mass is seventeen times the mass of Earth. Neptune’s composition is similar to that of Uranus. It is made up of several different rocks and ices and it is about 15% hydrogen and a little helium. This gas planet has the fastest winds in the solar system reaching 2,100 km per hour. Neptune also has it’s own internal heat source that radiates twice as much energy as it gets from the sun. Neptune orbits the sun at an average of 30.1 AU. It was the first planet found by mathematical prediction rather than observation. It ...view middle of the document...

Neptune’s sky contains the large moon Triton and it appears slightly smaller than a full moon on Earth. There are also smaller moons that are visible from the planet, ranging in sizes about half the size of a full moon from earth to sizes not distinguishable by the human eye. It is not likely that Neptune’s rings can be seen from its surface. It is not possible for humans to survive on Neptune’s surface like we do on Earth. It would take some serious adaptation.
If life were to adapt on Neptune’s moon Triton there would be a gorgeous view on Neptune in the sky. Triton is Neptune’s biggest moon. Its surface is rocky and cratered surface with volcanic mounds are pits of flowing icy lava. Triton is the largest of Neptune’s 13 moons. This unique moon is unusual because it is the only moon in the solar system that orbits in the opposite direction of its planet’s, Neptune’s, rotation, which is called a retrograde orbit. “Scientists think Triton is a Kuiper Belt Object captured by Neptune's gravity millions of years ago. It shares many similarities with Pluto, the best known world of the Kuiper Belt.” (NASA, 2013) The Kuiper Belt is a disc-shaped region of icy objects beyond the orbit of Neptune, which is billions of kilometers from our sun.

Triton was a phenomenon that is believed to have been captured by Neptune’s gravity millions of years ago. British astronomer William Lassell discovered Triton on October 10 1846. German astronomers, Johann Gottfried Galle and Heinrich Louis d’Arrest discovered Neptune just 17 days before Triton. NASA’s Voyager 2 observed it once, which is the only spacecraft to fly past Neptune and Triton. The spacecraft measured...
