The Planet Neptune :: Space Astronomy

The wonders of the great planet of mysterious Neptune "5,4,3,2,1, LIFTOFF! I think I see something on the radar, it looks to be as if it's a planet! I think I have visual contact, blue, thick clouds and maybe a little liquidy substance, probably water. Wait a minute, I think it's Neptune! We have to report this to the mission control." Neptune, the last planet in the solar system after the planet Pluto was considered not a planet. You might think Neptune and Earth are the same size by just looking at it but it?s not. Neptune is so big that it could fit sixty Earths inside. It is the fourth largest planet in the solar system. Neptune use to share an orbit with Pluto. That declined when Pluto was considered not a planet anymore. The gravity on Neptune is slightly dense. I?ll give you an example, I currently weigh 60 pounds on Earth, and on Neptune I would weigh about 71 pounds. That means there?s about an 11-pound difference on Neptune. The orbit of Neptune is unique. This is because Pluto?s eccentric orbit crosses between Neptune?s orbit. Take an estimate, how long do you think a year on Neptune would be? You probably answered any where between 60 and 90 years. Unfortunately you?re wrong. The correct answer is 165 Earth years. That?s a really long time! A day on Neptune is 16.1 Martian hours or 19.1 Earth hours. The atmosphere on Neptune is made out methane, hydrogen sulfide and water. The temperature on Neptune is 49K or 328ÂÂ °F. If you lived on Neptune (which you can?t!) you would boil. Neptune has four rings. Two of them are hard to see and are faded, Neptune?s rings are made out of dust. A scientist named Johann Gottfried Galle discovered Neptune. Voyager 2 visited Neptune. Neptune was discovered on September 23, 1846. Neptune was named after an Italian goddess named Poseidon or Nethunus or Neptune.
