How Has Information Bout Neptune Been Gatheres Essay

How has information about Neptune been gathered?

When Neptune was foremost seen by Galileo Galilei it was thought to be merely a star. Neptune was foremost observed by Johann Galle and Heinrich D’Arrest on the 23rd of September inn 1846. On August 25 1989 the Voyager 2 flew by the planet and it got 1000s of images which gave us most of the information we have about Neptune today. The 1000s of images that the Voyager 2 took were images of Neptune’s Moons and rings. This flyby by the Voyager 2 gave us most of the information we have about Neptune today. The Voyager is the lone ballistic capsule which has flown by Neptune and has gotten information.

In 1998 scientists used telescopes on Earth every bit good as telescopes in infinite to see Neptune’s pealing discharge ( the ring discharge are the rings of Neptune but at this point they were thought to be kind of like half rings around Neptune. The rings appeared to be a half molded because of Neptune’s Moons ) every bit good as its rings. Neptune has been studied from the land but it is a really ambitious undertaking due to the fact that the planet is a little disc shaped object and besides because Neptune’s images are really bleary because of the distance between Earth and Neptune. Earth’s atmosphere besides causes the images to be blurred. The Hubble ballistic capsule has besides been used to happen information about the planet Neptune. The Hubble ballistic capsule is a device which has been sent into infinite by NASA.

Neptune’s place in our solar system

Neptune is the eighth planet from our Sun and the fifth farthermost planet from our Earth. It is besides the last gas planet in our solar system. The distance between our Sun and Neptune is 30. 06 AU ( astronomical units ) . Neptune’s distance from our Earth is 29. 06 AU ( astronomical units ) .

Neptune’s orbit around the Sun

Neptune revolves/orbits around the Sun one time every 164. 79 Earth old ages or one time every 60. 190 Earth yearss. Neptune travels at an mean velocity of 12. 253 miles/hour or 19. 720 km per hr in its orbit around the Sun.
