The first thousand eight hundred and sixty chapters fly to Neptune

Feifei and Tiantian also followed Dad and started walking forward. Soon, they returned to the spaceship together.

After Zhao Zhongyao and the others returned to the spaceship, they put each of the eight amethyst gems away. Now they have got a total of eight amethyst gems. With four more amethyst gems, they can use the energy of amethyst gems to open the door of time and space.

As long as they can open the gates of time and space, they can go on interstellar voyages, go to Sirius, and finally uncover the Mayan star destruction event that occurred in the solar system 10,000 years ago.

‘Dad, we have got the eighth amethyst gem, we are getting closer and closer to our goal, we must continue to work hard to get all amethyst gems. ’

Feifei thought that they had already obtained eight amethyst gemstones, and was very happy, so he wanted to get all amethyst gemstones quickly so that he could go on interstellar travel.

After hearing Feifei’s words, Zhao Zhongyao smiled and said, ‘Okay, we’re going to Neptune, we’re going to look for the ninth amethyst gem. ’

‘Yes, we are going to look for the ninth amethyst gem. He also echoed one sentence every day.

After Zhao Zhongyao finished speaking, he started the spacecraft and flew towards Neptune.

The speed of the spacecraft was very fast, leaving Tianwei San for tens of thousands of kilometers in the blink of an eye. Because it is far away from the sun, there is less light in space, only some bright stars and some planets can be seen.

The scenery outside is so beautiful, everyone is still thinking about their next stop, Neptune.

Tiantian looked at Zhao Zhongyao happily at this time and said, ‘Dad, that ninth amethyst gem is on that planet, not just on Neptune! ’

Zhao Zhongyao took out the original amethyst gem and took a look and said, ‘according to the star chart, the ninth amethyst gem is on the largest moon of Neptune, which is on Triton. ’

‘On Triton, is this satellite very distinctive? He looked at Zhao Zhongyao and said every day.

‘Of course, this is a satellite with a diameter of more than two thousand kilometers, and it is the only planet in the solar system that revolves counterclockwise. It is also the coldest planet in the solar system, with a temperature of -235 degrees. Zhao Zhongyao said again.

At this time, Feifei looked at Zhao Zhongyao and said, "Dad, since we are going to Neptune, shouldn’t we first understand Neptune’s situation? As for the Triton, we will wait until later. It's not too late. ’

Hearing Feifei’s words every day, he also said, ‘Dad, then I will tell us about Neptune first! ’

After hearing what Feifei and Tiantian said, Zhao Zhongyao said with a smile, ‘haha, okay, let me tell you something about Neptune first! Since we are going to Triton, we must first understand the home planet of Triton-Neptune. ’

Next, Zhao Zhongyao taught the two children some knowledge about Neptune. Let's learn about it together.

Neptune is one of the eight planets in the solar system and the planet farthest from the sun in the known solar system. The semi-major axis of Neptune's orbit is 30.07 astronomical units, the revolution period is 164.8 years, the mass is 17.147 earth mass (the third, slightly larger than its neighbor Uranus), and the radius is 3.86 the earth radius (4th)

The highest magnitude of Neptune is about 7.67 magnitude, which requires the help of an astronomical telescope to observe it. Neptune is blue to the naked eye, and Westerners named it after the sea **** Neptune in Roman mythology.

The chemical composition of Neptune’s atmosphere is dominated by hydrogen molecules and helium. In addition, there are traces of methane in the atmosphere of Neptune, which is one of the reasons that make the planet blue. Neptune has a strong storm, and the measured wind speed is as high as 2100kmh. The temperature of the cloud top of Neptune is -218 degrees Celsius (55K), which is slightly higher than the temperature of the cloud top of Uranus.

It is speculated that Neptune is likely to have a hot interior with a core temperature of about 7000°C, similar to most known planets. Neptune's mass is slightly greater than Uranus, its density is slightly greater than Uranus, and its radius is slightly smaller than Uranus.

Neptune was discovered on September 23, 1846, and was the only planet that was accidentally discovered using mathematical predictions rather than observations. Astronomers use the perturbation of Uranus' orbit to infer the existence and possible location of Neptune.

The internal structure of Neptune is similar to that of Uranus. A planetary core is a mixture of rock and ice with a mass no more than one mass of the earth.

The total mass of Neptune's mantle is equivalent to 10 to 15 earth masses, rich in water, ammonia, methane and other components. As a planetary convention, this mixture is called ice, although it is actually a highly compressed superheated fluid.

This highly conductive fluid is also commonly referred to as a water-ammonia ocean. The atmosphere includes about 10% to 20% from the top to the center. The upper atmosphere is mainly composed of 80% hydrogen and 19% helium. The content of methane, ammonia and water increases with decreasing height.

The lower part of the inner atmosphere has a higher temperature and a greater density, and it gradually mixes with the superheated liquid in the planet's mantle.

The pressure in the inner core of Neptune is millions of times the atmospheric pressure on the earth's surface. By comparing the speed and oblateness, it can be seen that the mass distribution of Neptune is not as concentrated as that of Uranus.

The egg-shaped cyclones resembling the Great Red Spot of Jupiter and the Great White Spot of Saturn on Neptune rotate counterclockwise in a period of about 16 days, and are called the "Great Black Spot." Since the Great Dark Spot orbits Neptune every 18.3 hours, which is longer than the rotation period of Neptune, the latitude near the Great Dark Spot blows a strong westerly wind at a speed of 300 meters per second.

The **** spot may be a plume rising from the lower part of the atmosphere, but its true nature is still a mystery. However, on November 2, 1994, Hubble's observation of Neptune revealed that the Great Black Spot had disappeared.

It may just dissipate, or it may be temporarily hidden by other parts of the atmosphere. A few months later, the Hubble Telescope discovered a new dark spot in the northern hemisphere of Neptune. This indicates that Neptune’s atmosphere changes frequently, which may be caused by subtle changes in the temperature difference between the top and bottom of the cloud.

Neptune has 14 known natural satellites. Triton is the only large satellite. It was discovered by William Russell 17 days after Neptune was discovered. Unlike other large satellites, Triton moves in a retrograde orbit, indicating that it was captured by Neptune. A Kuiper belt object.

It is close enough to Neptune to be locked in a synchronous orbit. It will slowly approach Neptune via a spiral orbit. When it reaches the Roche limit, it will eventually be torn apart by Neptune's gravity. Triton is the coldest celestial body measured in the solar system, with a temperature of -235°C (38K). The second known satellite of Neptune (arranged by distance) is the irregularly shaped Triton, whose orbit is one of the most eccentric satellites in the solar system.

From July to September 1989, Voyager 2 discovered six new Neptune satellites. Among them, the irregular shape of Triton is famous for having the largest volume that cannot be turned into a sphere by its own gravity under its density. Although it is the second most massive satellite of Neptune, it is only 1,400 the mass of Triton.

The four satellites closest to Neptune, Triton, Triton, Triton, and Triton, orbit within Neptune’s ring. The second outer Triton was observed during its occultation in 1981.

At first, the cause of the occultation was attributed to the arc on the planetary ring, but according to the observation of Voyager 2 in 1989, it was discovered that it was caused by the satellite. In 2004, five new irregularly shaped satellites discovered between 2002 and 2003 were announced. Since Neptune is named after the sea **** in Roman mythology, its moons are all named after the lower sea god.
