Jupiter is the largest and most important planet in the solar system. It also has many satellites and is one of the most observed celestial bodies that the naked eye. In the field of vision of small astronomical telescope, Jupiter's stripes, large erythema and four Galileo satellites are the goals of astronomical enthusiasts.

On the sky, the planet and the moon are just running to the same degree, and the angle distance between the two reaches the closest. This day is called "planetary moon". When the angle between the moon and the planet is close to a certain extent, the phenomenon of "the moon cover the planet" will occur.

Liu Dongyu, director of the Tianjin Popular Science Writers Association and a member of the Beijing Astronomical Society, introduced that Jupiter's monthly moon is not uncommon. As long as the moon "chase" Jupiter once, it will stage a Jupiter Moon. This day is at least once a month, but the observation conditions are different. The highlight of this Jupiter's moon is: Jupiter and the moon tonight are very bright; the angle between the two is very close; at this time, most parts of my country have entered autumn. When the autumn is high, the weather is clear. It is also suitable for the public to conduct outdoor moon watching activities.

After today, the bright Jupiter and Yuanyue will rise, and it can be seen all night. For the northern hemisphere observer, Jupiter is less than 3 degrees above the left to the left, that is, the diameter of 5-6 full-moon vision. Over time, Yuanyue gradually began to approach Jupiter. The distance between Jupiter and Yuanyue around 23 pm reaches the moment, that is, the moment of "combination". At this time, the height is higher and easy to observe. Interested public can watch the sky in the southeast at about 20:00 tonight. Jupiter and Yuanyue are accompanied by each other.

Liu Dongyu said that comprehensively considering the time and celestial brightness factors, in the 14 Jupiter Monthly this year, in addition to watching the public with the naked eye, if the public in our country is watching with the naked eye You can take the picture of the "same frame" with Jupiter, and you can also take the colorful stripes of Jupiter's surface and the big red spots on its equator and 4 Galileo satellites.
