How Has Information Bout Neptune Been Gatheres EssayHow has entropy about Neptune been gathered?When Neptune was first filln by Galileo Galilei it was thought to be just a star. Neptune was first discovered by Johann Galle and Heinrich DArrest on the 23rd of September inn 1846. On August 25 1989 the Voyager 2 flew by the artificial satellite and it got thousands of pictures which gave us most of the information we have about Neptune today. The thousands of pictures that the Voyager 2 took were pictures of Neptunes moons and rings. This flyby by the Voyager 2 gave us most of the information we have about Neptune today. The Voyager is the only spacecraft which has flown by Neptune and has gotten information.In 1998 scientists used telescopes on earth as well as telescopes in space to see Neptunes ring arcs (the ring arcs are the rings of Neptune but at this point they were thought to be sort of like half rings around Neptune. The rings appeared to be a half determine because of Neptunes moons) as well as its rings. Neptune has been studied from the ground but it is a very contest task due to the fact that the planet is a small disk shaped object and alike because Neptunes images are very blurred because of the distance between Earth and Neptune, Earths asynchronous transfer mode also causes the images to be blurred. The Hubble spacecraft has also been used to find information about the planet Neptune. The Hubble spacecraft is a device which has been sent into space by NASA.Neptunes position in our solar musical arrangementNeptune is the 8th planet from our sun and the 5th farthest planet from our Earth. It is also the last gas planet in our solar system. The distance between our sun and Neptune is 30.06 AU (astronomical units).Neptunes distance from our earth is 29.06 AU (astronomical units).Neptunes orbit around the SunNeptune revolves/orbits around the Sun once every 164.79 Earth historic period or once every 60.190 Earth days. Neptune travels a t an average speed of 12,253 miles/hour or 19,720 km per hour in its orbit around the sun.
