The most anticipated natural phenomenon in September is about to be staged. Astronomical popular science experts introduced that Tianyu will usher in Jupiter on the 27th. At the time of the sun, Jupiter just happened to be near the recent point (Jupiter's nearest point from the sun on the orbit of the sun), which means that Jupiter is closer to the earth and looks bigger and brighter.

As one of the most pronounced celestial bodies that are the easiest to observe, the colorful Jupiter in the view of the telescope is deeply loved by astronomical enthusiasts. Jupiter is the fifth planet from the sun, and it is also the planet with the largest volume and quality in the solar system and the fastest rotation. Because the Jupiter's revolution cycle is about 12 years, it is called the "age star" in ancient China, and this is also the main origin of the concept of the "twelve earth branches" in traditional Chinese culture.

As of now, more than 5,000 exogenous planets that humans have discovered (outer planets refer to planets that surround the sun outside the sun), most of them are gaseous planets like Jupiter -they do not have the earth like the earth. Hard rock shells, wrapped in thick hydrogen and 氦 elements on the surface.

On the 27th, this huge gaseous planet's performance in the night sky will usher in a climax -Jupiter rushes. Jupiter rushing the sun means that Jupiter and the Sun just separated from both sides of the earth. The three of them were almost a straight line. On the day, Jupiter's side was illuminated by the sun to the earth.

Liu Dongyu, director of the Tianjin Science Popularization Writers Association and a member of the Beijing Astronomical Society, introduced that Jupiter's rushing in the sun is not a rare natural phenomenon. This is because Jupiter and the earth's club cycle is about 399 days, which also means that it is almost about 13 months every 13 months. There will be a Jupiter once.

People can see Jupiter, mainly because Jupiter reflects the sun, so its brightness is largely affected by the distance from the earth. Since September, Jupiter's brightness has continued to increase. During the time around the day, Jupiter can reach about -2.94 at the brightest.

"If the weather is clear, Jupiter must be the most unsolved star that night. It rises from the southeast before dusk. It falls in the southwest before dawn. It can be seen all night. Observation of tube telescope or small telescope observation, you can not only see the colorful parallel stripes and the red spots on the south side of the equator, you can also see 4 Galileo satellites surrounding Jupiter. Of course, watching Jupiter is not limited to the day of the day, In fact, the difference between Jupiter saw Jupiter in a month before and after, "Liu Dongyu said.
