Neptune, the eighth planet in the Solar System is located between Uranus and Pluto and at times, it is referred to 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 the Earth and Neptune is about 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 at www.coolspacefacts.com.
The astronomers from early times detected Neptune including Galileo. Nonetheless, Galileo didn't comprehend he was seeing a planet. In early times, there were no powerful telescopes to help the astronomers and researchers discern planets. Hence, when they found Neptune, the astronomers didn't observe the disk shape of the planet.
The astronomers and investigators found this planet using 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. Another French astronomer did the calculations and got similar results to the British astronomer. Utilizing the calculations created by the French Astronomer, Johann C. Galle discovered Neptune at September 23, 1846. Since their calculations were instrumental its discovery, it was attributed to the French and British astronomers.
Because of its blue appearance, Neptune was named after the Roman god of the sea. Its naming follows the rest of the planets of the solar system which are all named after Roman gods. Get Cool Space Facts here!
Iron, nickel and other silicates make up this planet. The mantle of Neptune mainly consist of methane, water, ammonia and other chemical compounds. Neptune's mantle is very hot with temperatures which vary from 3000 to 5000K. The atmosphere includes 80% hydrogen, 19 percent of helium and 1 percent of ammonia, water 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. There is a high possibility that you will find far more moons which 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; Adams, Galle, LeVerrier, 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.
