Neptune Planet All Information You Should Know

Neptune Planet

Neptune Planet is the eighth planet in our solar system and it is also the most distant planet from the Sun. It is the fourth largest planet in size and it is the third largest planet in weight. Neptune cannot be seen with normal eyes and therefore Neptune Planet was not discovered by our ancestors, it is also very difficult to study Neptune from the Earth, and that’s why Neptune did not find any telescope, but Neptune was discovered by mathematical prediction.

Discovery

When the great scientist Galileo Galilei started looking at the space from his telescope, he made the drawing of planets and stars, upon which the planets and stars were shown by making points. The 1 point in those drawings was exactly the same place as Neptune today, but Galileo understood this point as a star and Galileo was not credited for the search of Neptune. In 1821 Alexis Bouvard published a theoretical table for Uranus’ Orbit, but when the Observation was done, there was a significant difference in the calculation of the orbit. Then Alexis Bouvard said that there is something unknown that is disturbing Uranus’s orbit by gravitational interaction. In 1843, John Cauch Adams was also researching the orbits of Uranus, he also expressed the possibility of being a new planet there.

In 1845, Urbain le Verier also claimed to be a new planet after Uranus, according to its calculations. Due to so many predictions of the new home, astronomers began searching for this new planet. Finally, on September 23, 1846, we discovered Neptune. Neptune was discovered by two different scientists, whose names are Adams and Urbain le Verier, but Urbain le Verier was credited with the discovery of Neptune because the Neptune’s description of the position of Neptune was within its 1-degree accuracy , But from the position of Neptune, told from Adams, actually Neptune was within 12 degrees. According to Accuracy, Urbain le Verier was more correct

Name of Neptune

This planet was named by Neptune Urbain le Verier. It was named Neptune on the basis of the sea god according to the Neptune Roman civilization.

Distance and Orbit

Neptune is about 4.50 billion kilometers away from our Sun, which is equivalent to 30.1 astronomical unit (AU). Whenever it is at the shortest distance from the Sun, its distance from the Sun is 29.81 astronomical units (AU). But when it is the most distant of the Sun, its distance from the Sun is 30.33 Astronomical Units (AU). Neptune completes one revolution of the Sun in 164.79 years, Neptune is tilted to approximately 28.32 degrees on its axis, and our earth is also tilted to about 23 degrees.

That’s why Neptune also has the same weather as our earth. But due to Neptune’s Orbital Period being longer, one season will be nearly as long as 40 years of Earth. Neptune is a gaseous planet that causes its different parts to move at different speeds, The rotational period of the planet of Equatorial region is 18 hours while its rotational period of Polar region is 12 hours.

Neptune Planet Structure

Neptune is about 17 times bigger than ours. Its gravity is 11 m / s2 which is 1.14 times more than the Earth’s gravity. The Equatorial Radius of this planet is 24764 kilometers, which is 4 times more than the Radius of our Earth. The internal structure of the planet Neptune is similar to the Uranus Planet. Its inner core is made of iron, Nickel, and Silicate and it is about 1.2 times heavier than the Earth. Its core has a pressure of 7 Megabar which is 2 times more than the core of the Earth and its core temperature is 5400 Kelvin. The mantle layer of Neptune is about 15 times heavier than the Earth, and in this too, water-ammonia like Uranus is found in excessive amounts, This fluid is Highly Conductive, which is also called Water Ammonia Ocean. Like other Giant planets, Neptune also produces Internal Heat, which releases about 2.1 times more energy than it receives from the sun.

Atmosphere of planet Neptune

In the outer environment of Neptune, 80% hydrogen and 19% helium are mostly found. Traces of methane and other elements have also been found in its environment. The planet Neptune is also called Ice Giant because the planet is very cold and its average temperature ranges below -214 degrees Celsius. In 2007, the South Pole of Neptune was considered to be the hottest place on the planet, where the temperature was around -200 ° C.
The pole was hot because in the last 40 years, this southern pole of Neptune was on the side of the sun.  Very strong winds blow on the Neptune Planet. The fastest wind speed here is more than 600 m/s, which is almost equal to the supersonic flow. The direction of most winds running on Neptune is completely opposite of its rotational direction.

The storm on the planet Neptune

In 1989, Voyager 2 discovered a major storm on this planet during its Neptune flyby, which is known as “The Great Dark Spot”, Because it was dark in color. The Great Dark Spot is compared to the Great Red Spot of the Jupiter Planet, but this storm soon disappeared, which was confirmed by Hubble Space Telescope on November 2, 1994. In addition to Great Dark Spots on Neptune, white spots are also found, which are one of the storms in the upper part of the atmosphere, those storms are also called scooters.

Satellite of Neptune Planet 

Neptune’s Planet 14 satellites have been discovered so far. Triton is the planet’s largest satellite of Neptune, which was discovered 17 days after the discovery of Neptune. Triton is a very cold satellite, where the average temperature is around -235 ° C. It is believed that Triton Neptune is not a natural satellite, perhaps it would have been a dwarf planet, but Neptune would have pulled it out of its gravity. Neptune’s Orbit has 99.5% mass of Triton only. This satellite is almost round in size, while the rest of Neptune’s satellites are of irregular size.
