Neptune, which is the eighth planet in the Solar System is found between Uranus and Pluto and occasionally, it’s known as the Blue Giant. Its diameter is near 49,500 km in diameter, and so it’s nearly four times the size of the Earth. The distance between Neptune and the Earth is nearly 4. 4 billion kilometers, and thus, you cannot see it with your naked eyes. Even in the event that you use the binoculars, you can’t see the planet nicely. Below we will discuss some of the compelling facts about Neptune from coolspacefacts.com.
Neptune was observed by the astronomers from ancient times including Galileo. Nonetheless, Galileo didn’t comprehend he was seeing a planet. In early times, we didn’t have telescopes that were sufficiently powerful to assist the astronomers and researchers identify planets. Thus, when they discovered Neptune, the astronomers did not note the disk shape of the planet.
The astronomers and researchers discovered this planet through mathematical calculations. In 1843, a mathematician and astronomer in Britain was crucial in calculating the exact location of Neptune. Based on the calculations, the astronomer estimated that Neptune had been one billion kilometers farther away from the Sun compared to Uranus. Yet another French astronomer did the calculations and obtained comparable results to the British astronomer. Utilizing the calculations created by the French Astronomer, Johann C. Galle discovered Neptune at September 23, 1846. This discovery was credited to the British and French astronomers since their calculations were key its discovery.
Neptune got its name after the Roman god of the sea because of its blue appearance. Its naming follows the rest of the planets of the solar system which are all named after Roman gods.
This planet is made up of nickel, iron and other silicates. The mantle of Neptune mainly consist of methane, water, ammonia and other chemical compounds. Neptune’s mantle is quite hot with temperatures that range from 3000 to 5000K. The atmosphere consists of eighty percent hydrogen, 19% of helium and one percent of water, ammonia and methane.

The blue color which characterizes this planet is a result of the presence of methane in its atmosphere. It absorbs the red light that comes from the sunlight then reflects it in the color blue in space.
Thirteen moons that revolve around Neptune till now have been discovered by astronomers and researchers. It’s quite possible that you will find far more moons that are yet to be found.
The first spaceship to get to Neptune was known as the Voyager 2, and it did in 1989. It took images of the planet which helped the researchers in discovering that the planet has five rings. These rings are; Galle, LeVerrier, Adams, Lassel, and Arago. People believe that these rings formed a single planet when one of the moons of Neptune got very close and broke into millions of particles due to the gravity in Neptune.
