The History Of Neptune Before we dive into the various facts, figures, and numbers concerning the planet known as Neptune, let's first talk about its history and its discovery. Because it's a little more important than you might expect it to be. Some of the earliest recorded observations ever made through a telescope, Galileo's drawings on 28 December 1612 and 27 January 1613 contain plotted points that match up with what is now known to be the position of Neptune. On both occasions, Galileo seems to have mistaken Neptune for a fixed star when it appeared close—in conjunction—to Jupiter in the night sky; hence, he is not credited with Neptune's discovery. At his first observation in December 1612, Neptune was almost stationary in the sky because it had just turned retrograde that day. This apparent backward motion is created when Earth's orbit takes it past an outer planet. Because Neptune was only beginning its yearly retrograde cycle, the motion of the planet was far too slight to be detected with Galileo's small telescope. In 2009, a study suggested that Galileo was at least aware that the "star" he had observed had moved relative to the fixed stars. In 1821, Alexis Bouvard published astronomical tables of the orbit of Neptune's neighbour Uranus. Subsequent observations revealed substantial deviations from the tables, leading Bouvard to hypothesize that an unknown body was perturbing the orbit through gravitational interaction. In 1843, John Couch Adams began work on the orbit of Uranus using the data he had. He requested extra data from Sir George Airy, the Astronomer Royal, who supplied it in February 1844. Adams continued to work in 1845–46 and produced several different estimates of a new planet. In 1845–46, Urbain Le Verrier, independently of Adams, developed his own calculations but aroused no enthusiasm in his compatriots. Le Verrier by letter urged Berlin Observatory astronomer Johann Gottfried Galle to search with the observatory's refractor. Heinrich d'Arrest, a student at the observatory, suggested to Galle that they could compare a recently drawn chart of the sky in the region of Le Verrier's predicted location with the current sky to seek the displacement characteristic of a planet, as opposed to a fixed star. On the evening of 23 September 1846, the day Galle received the letter, he discovered Neptune just northeast of Phi Aquarii, 1° from.. 9. Orbits and Rotations As you head to the outer reaches of the solar system, Neptune is "officially" the last planet in our solar system (if you don't believe that Pluto is a planet...), and as such, its time around the sun isn't so much about years rather than lifetimes. Because one orbit around the sun is about 165 years! The oldest person to ever live hasn't made to 165 years (unless you count certain religious tales and the mythological stories, just saying). In 2011 Neptune completed its first 165-year orbit since its discovery in 1846. For a day though, it's actually faster than its twin in Uranus, because it has a day of about 16 hours. So that right there is a bit of a conundrum if you will. Because IF we were ever to make it to Neptune (and we'll get to that), the days on there would be shorter, but not impossible to adjust to. But to try and adjust to a year-cycle that is double the average lifespan of a human? That would take some doing. Though I'm sure some of you would try and make it work out. 8. Seasons As for seasons on the planet Neptune, like many of the other planets, it has Spring Summer Winter and Fall, it's just that they last about 40 years each and can cause extreme temperature changes to the planet when they occur. 7. Storms and Spots In 1989, the Great Dark Spot, an anti-cyclonic storm system spanning 13,000 × 6,600 km, was discovered by NASA's Voyager 2 spacecraft. The storm resembled the Great Red Spot of Jupiter and it was large enough to hold the ENTIRE Earth within it. Some five years later, on 2 November 1994, the Hubble Space Telescope did not see the Great Dark Spot on the planet. Instead, a new storm similar to the Great Dark Spot was found in Neptune's northern hemisphere. The Scooter is another storm, a white cloud group farther south than the Great Dark Spot. This nickname first arose during the months leading up to the Voyager 2 encounter in 1989, when they were observed moving at speeds faster than the Great Dark Spot (and images acquired later would subsequently reveal the presence of clouds moving even faster than those that had initially been detected by Voyager 2). The Small Dark Spot is a southern cyclonic storm, the second-most-intense storm observed during the 1989 encounter. #InsaneCuriosity#Neptune #TheSolarSystem
