8 Facts about the Planet Neptune, Know Everything about the Planet Neptune

Sundries, fun facts Neptune – Talking about planets is always fun, especially since every planet in the solar system has its own unique facts. Likewise, the planet Neptune has some unique facts. To find out every unique fact that exists on Neptune, you can see this article, Sinaumed’s.

About the Planet Neptune

The planet Neptune is the farthest planet from the sun. Neptune is also the only planet in the solar system that is not visible to the naked eye. This planet was also first discovered on September 23, 1846.

Before being discovered directly, this planet had been predicted using mathematical calculations made by Urbain Le Verrier, a French mathematician. Neptune’s name itself is taken from the name of the sea god in Roman mythology.

The diameter of the planet Neptune is estimated to be 49,244 km or about four times larger than planet Earth. Meanwhile, the average distance of the planet Neptune to the sun itself is 4.5 billion kilometers or 30 AU.

Sunlight takes 4 hours to reach Neptune. Neptune is so far from the sun that midday on this planet looks like a faint twilight. One day on Neptune equals 16 hours on planet Earth. This is also because the planet rotates once on its axis (with the rotation of Neptune) it takes 16 hours.

Meanwhile, the planet Neptune takes approximately 165 years to circle the sun in one rotation. In 2011, Neptune has completed its first 165-year orbit since its discovery in 1846.

Sometimes, Neptune is even farther from the sun than the dwarf planet Pluto. Pluto’s orbit is very eccentric and oval in shape and carries it into the orbit of Neptune for 20 years every 248 years.

However, the planet Pluto will never be able to crash into Neptune. This is because for every three revolutions Neptune makes around the sun, Pluto makes two revolutions. Pluto’s orbit is closer than Neptune’s for 20 years every 248 years. Neptune’s axis of rotation is tilted 28 degrees with respect to the plane of its orbit around the sun, very similar to the axes of Mars and Earth.

This causes Neptune to experience seasons similar to those experienced on Earth. However, each of the four seasons on the planet then lasts for more than 40 years. Neptune is also one of the ice giants in the solar system, which is almost the same as Uranus.

Most of the mass of the planet Neptune itself consists of hot solid liquid and consists of “ice” materials such as water, methane, and ammonia which is above a small rocky core. Of the other giant planets, Neptune is the densest.

Scientists also think there may be oceans of superheated water beneath Neptune’s cold clouds. Neptune also doesn’t have a solid surface and Neptune’s core itself is composed of iron, nickel, and silicates, with a mass about 1.2 times that of Earth.

The pressure in Neptune’s core itself is estimated to be millions of times greater than the pressure on the surface of the Earth. The temperature at the planet’s core alone can reach 5,400 K. Neptune’s atmosphere is mostly composed of hydrogen and helium with a small amount of methane.

As with the planet Uranus, the absorption of red light by methane in the atmosphere is part of what gives Neptune its blue color. However, Neptune’s bright cerulean color is different from the turquoise color of Uranus. This can happen because the methane substance in Neptune’s atmosphere, like Uranus, is thought to have an unknown component that is thought to have contributed to Neptune’s color.

Neptune is the windiest planet in the solar system. Despite its great distance and very low energy input from the sun, Neptune’s winds can be three times as strong as Jupiter’s and nine times as strong as Earth’s. These winds also carry clouds of frozen methane around the planet at over 2,000 kilometers per hour.

In fact, the strongest winds on Earth alone reach only about 400 kilometers per hour. The planet Neptune is known to have 14 satellites. Neptune’s largest satellite, Triton, was discovered on October 10, 1846, just 17 days after the planet Neptune was discovered. Neptune has at least five main rings, named Galle, Leverrier, Lassell, Arago and Adams. This ring is also thought to be relatively young and shorter-lived.

Neptune Planet Facts

Planet Neptune is one of the planets which is also called the blue planet besides Earth. This planet is also known as a troublesome planet because it bears the orbits of the planets around it.

This planet also has a gravitational field of 11.15 m/s² with a magnetic field 27 times the strength of Earth’s magnetic field. Because it has this great power, Neptune often disturbs the nearby planet, namely Uranus.

In the past, it was also thought that there was a large moon, Planet Neptune, which was thought to be a small planet and could orbit the sun near Neptune. This month is also known as Triton. The planet Neptune is farthest from the sun.

In addition, this planet also has a name that comes from the name of the Roman god of the sea. It has the fourth largest diameter by mass of the solar system. Below are fun facts about Neptune that you need to know:

1. Taken from the name of Ancient Rome

Neptune’s name is taken from the name of the Roman sea god who uses the same name. At first, this planet was given the name Le Verrier. This name is taken from Jean Joseph Le Verrier as an astronomer who first discovered this planet. Later, this name was changed to God Neptune because it has a new color like the color of the ocean and this name was also trusted in Ancient Rome.

2. Accidentally Discovered

Neptune is very far from the sun and earth. In addition, its existence is also very difficult to find at night.

Galileo, as the first person to see this planet. At first, he also thought of Neptune as a star and not a planet. The existence of this planet was discovered by scientists who were observing the irregular orbit of Uranus.

This has led to various speculations that there are other planets trying to attract Uranus so that they can get closer to it. Not long after, this speculation turned out to be a reality and Neptune was finally discovered by scientists in 1846.

3. Has the same age as the sun

Another interesting fact is his age. The planet Neptune is older than Earth, which is 1 billion years older than planet Earth. Earth itself as a place of residence of mankind then has an age of around 4.5 billion years, while on the planet Neptune it is around 5.5 billion years old. In other words, the planet is then about the same age as the sun.

4. Farthest and Oldest Planet

Neptune is one of the planets that is located at the far end of the solar system. Previously, there was Pluto which was once called the farthest planet. However, in 2006, the International Astronomical Union finally determined that Pluto is not the smallest planet. Because of this, Neptune was finally designated as the planet that has the farthest location in the solar system.

In addition, this planet is also a planet that is slower (in its movement) when compared to other planets. This is also because this planet in one orbit takes about 164.8 years in earth time.

5. Blue Planet

Not only the earth, the planet Neptune also has the nickname “blue planet” because it has an atmosphere consisting of helium and hydrogen. The atmosphere on Neptune also consists of methane, ammonia, water and ice. This methane content also makes Neptune a blue planet. In addition, the atmosphere and oceans cover about 70% of the planet’s surface.

6. Always Causing Trouble

The planet Neptune is also often referred to as a planet that always causes problems. This is because this planet can often attract one of Triton’s natural satellites so that it can get closer to the surface of this planet. In addition, this itself is caused because Neptune is the second planet that has a strong gravitational force after Jupiter. Therefore, it’s no wonder that this planet is nicknamed the “Problem Maker” planet.

7. Had a Scary Storm

Hurricane as a natural phenomenon that can cause a lot of losses. Not only on Earth, but also on Neptune . On the planet Neptune, it turns out that it also has storms and storms that occur are very strong and frightening when compared to the storms that occur on Earth.

The storms that exist on Neptune itself were first discovered by Voyager 2 in 1989 specifically to then examine this planet more deeply. Voyager 2 also found the fact that there are two dark spots or dark blue dots which are known to be major storms that have occurred on Neptune. One of these storms itself has the size of the earth and has strong winds with a speed of 1,340 km per second.

8. Diamond Rain

Unlike on Earth, the rain that occurs on Planet Neptune is diamond rain. This is known from research conducted by an international team of scientists using the X-ray Linac Coherent Light Sources (LCLS) laser from the Linac National Accelerator Laboratory SLAC.

Through research they also found that the carbon material that is abundant on Neptune directly and transitions into diamond rain. This process is then tested by scientists with experiments. In this experiment, they also found that when carbon was compressed into diamond, the remaining atoms split into hydrogen, leaving practically no carbon at all. In other words, all this carbon has then turned into diamonds.

Smart Boy Science Comic: The Solar System

This Universe is so amazing. The universe is so big, with a sprinkling of stars, moon, comets and other heavenly bodies, it is really interesting for us to study. The sun that looks only as big as a soccer ball is actually much bigger than the earth we walk on! How could that be…?

All the stars visible in the night sky are members of the Milky Way galaxy. Everything looks small because it is very far from Earth. The star closest to Earth is the Sun; its average distance is 149,600,000 km. At that distance, sunlight takes 8.3 minutes to reach the Earth’s surface.

The sun is not a single star, he has neighbors, you know ! The closest star to the Sun is Proxima Centauri; it is 4.423 light years from Earth. This means that the light leaving Proxima Centauri will only reach Earth after 4,243 years. Comets, shooting stars, satellites, meteors, they all exist in our solar system. The moon that we see at night has no source of light. How come? Why can meteors fall to hit the Earth?

We can learn about the solar system. For example, what particles make up the sun. Any particles that make up the planets and other celestial bodies. Intrigued, right… let’s read and listen to this science comic! Hopefully increase knowledge and keep the spirit of learning to achieve goals.
