The flyby allowed for the study of the planet’s atmosphere, magnetosphere, rings, and moons. The Voyager 2 passed within 1,864 miles off Neptune’s the North Pole, making it the closest approach made by Voyager 2. The flyby was conducted by NASA’s Voyager 2 in August 1989. Neptune has only been viewed up-close by a spacecraft once since its discovery. Up-close Observation Of Neptune Happened Only Once Standing on the surface of the planet without sinking is, however, not possible as it is a ball of gas and ice. The gravitational force on Neptune is just 0.17 times stronger than the earth’s gravity. Some scientists reckon that Triton is slowly spiraling towards Neptune. This observation supports a hypothesis in the scientific community that the planet’s gravitational pull probably captured Triton. It orbits the planet in the opposite direction relative to its other moons. Neptune has 13 moons (plus an additional one awaiting confirmation) that are named after Greek sea gods and nymphs. Neptune's Moons Are Named After Greek Gods The planet is mentioned in science fiction films such as Event Horizon, cartoon series like Futurama, and in the “Sleep No More” episode of Dr. Neptune thus once again acquired its title as the furthest planet from the sun.ĭespite its distance from the earth, the planet is frequently referenced in pop culture and fiction. The decision led to the demotion of Pluto to a dwarf planet. The discoveries led to the re-emergence of a long-held question – what is a planet? In one of the most controversial decisions in the assembly’s history, a resolution was passed, which standardized the definition of a planet. ![]() The assembly was preceded by the discovery of several “Pluto-sized” planet-like bodies such as Haumea, Eris, Makemake, and Sedna in the Kuiper Belt. In August 2006, the matter of distant planets was discussed at the International Astronomical Union General Assembly. For example, during the period between 19, Pluto was seen to orbit closer to the sun compared to Neptune. Pluto’s orbit was, however, observed to be very elliptical, meaning that in some periods, Pluto’s orbit was closer to the sun than that of Neptune's. Following the discovery of Pluto, the title was stripped from Neptune. Pluto was then discovered in 1930 and at that time, was classified as the most distant planet from the sun. After the discovery in 1846, Neptune was the furthest planet from the sun. One could argue that this has not always been the case. Neptune is the furthest planet from the sun. The rings are named after astronomers associated with discoveries about the planet. Neptune has five rings (Adam, Galle, Arago, Lassell, and Le Verrier) that are very difficult to see compared to the bold and bright rings of Saturn. Planetary Rings Of Neptune Are Difficult To See Hydrocarbon snowflakes formed in the atmosphere usually melt before they get to the planet’s surface. Hazes of smog formed by hydrocarbons are a dominant feature of the upper atmosphere. Its distinct blue color also helps to distinguish it from Uranus. The planets’ deep blue color is derived from icy methane particles. For comparison, the strongest winds on earth only hit at about 250 miles per hour. Recorded wind speeds on the planet reach 1,250 miles per hour, which is comparable to the top speed of a US F/A-18 Hornet fighter jet. The atmosphere is also known to contain icy clouds and by far the fastest winds in the solar system blow here. The atmosphere on Neptune is incredibly thick and is comprised of hydrogen (74%), helium (25%), and methane (1%). Neighbouring Pluto (a dwarf planet) is much colder with temperatures of -400 degrees Fahrenheit. An unprotected human being would probably freeze in seconds if exposed to such temperatures. Temperatures at the top of clouds in Neptune are estimated to be about -366 degrees Fahrenheit. Neptune Is The Solar System's Coldest Planet Finally, a decision was made that gave both mathematicians equal recognition for Neptune’s discovery. The finding resulted in an international dispute with two opposing sides battling in support of Adam and Le Verrier, respectively. The credit for the discovery of the planet was given to Le Verrier, a French mathematician and John Adams, an English mathematician who had both predicted the existence of a “Planet X.” In 1846, the planet was found by Johann Galle, a German astronomer. The planet was the last to be discovered as it was not visible to the naked eye. ![]() Neptune is named after the Roman god of the sea and is one of the fascinating planets in the Solar System. ![]()
