According to astronomical popular science experts, as a planet that is currently known to the edge of the solar system, Neptune will be rushed on September 17th. Among the 10 days before and after, if the weather is fine, the public interested in the public uses an astronomical telescope to supplement the corresponding corresponding to corresponding The star map software is expected to observe this light blue mysterious planet.

After Tianwang Xing was discovered, astronomers used the use of the Tianwang Xing's track to speculate the existence and possible position of another planet. In 1846, the "speculative planet" was discovered by German astronomer Galler, and was subsequently named Neptune. The discovery of Neptune shows that the calculation of science and precision observation is equally important. It is an indispensable and common means in astronomical research.

"The discovery of Neptune should undoubtedly be attributed to the correct calculation based on scientific theory. Therefore, the discovery of Shanghai Wang Xing in the history of astronomy has been called the" discovery of the pen tip. " Peng said.

The so -called rushing sun refers to other planets, asteroids and the sun that is running on the orbit of the earth. The three are on both sides of the earth. The three are almost a straight line. This is a good opportunity to observe the planet or asteroid.

"Every time the sun is rushing, the Neptune is closest to the earth, the most diameter and the highest brightness. As the sun falls, Neptune rises from the East Horizon. It can be observed at night. "Xiu Lipeng said.

Neptune does not glow, and it is completely reflected in the sun, so the brightness is not high, and it is only 7.8 when it is rushing to the sun.

Xiu Lipeng reminded that if you are interested in the public, it is easier to find the location of Neptune in the sky, and you can find a place far away from urban lights and high air transparency. In addition to using astronomical telescopes, you also need to use the help of star map software. In order to better see the style of this light blue planet.
