Jupiter and Earth "Meet" on September 26

The largest planet Jupiter in the solar system will run on September 26 to the closest position of the cycle of the meeting cycle. According to Wang Kechao, the science science director of Zijin Mountain Observatory of the Chinese Academy of Sciences, the Jupiter and the Earth's "meeting" was about 3.95 astronomical units, or about 591 million kilometers. What's the matter with Jupiter and the earth? What does it have to do with the well -known "Jupiter Chongki"? Science experts from the Chinese Academy of Sciences Zijin Mountain Observatory's science experts will confuse you one by one.

Jupiter is the fifth planet from the sun and the largest planet in the solar system. Its quality is about 2.5 times the total quality of other planets of the solar system. This huge quality has produced a strong gravity, allowing it to capture many asteroids and comets near its orbit. Jupiter is therefore known as the "big broom" in the solar system, and has also become a "protector" for the earth's invasion of celestial bodies to a certain extent.

Wang Kechao introduced that Jupiter and the earth revolved around the sun, and their distance is far away. The meeting cycle of these two planets is 399 days, which is about 13 months. In each cycle, Jupiter and Earth will usher in a "meeting". However, because the orbits running around Japan are ellipse and there is an inclination, the closest distance between the earth and Jupiter during each time the cycle will be different.

Following the "meeting" on the 26th, Jupiter will usher in Jupiter at 3:33 on the 27th. Outer planets such as Jupiter have been bright before and after the day, and have a large diameter. It is suitable for observation. It feels close to the "meeting" of wooden land. "But in fact, there is a difference between the moment when the rushday and the wooden land reaches the nearest distance." Wang Kechao said that the so -called "rushing day" refers to the difference between the Jupiter's and the sun's heart. Jupiter's rotation around the sun to the same side of the sun is approximately lined up in a straight line. At this moment, it is closer to Jupiter and Earth's "meeting", but it is not consistent.

And this year Jupiter rushes, Jupiter is located near the recent point, which means that Jupiter is closer to the earth and looks bigger and brighter. The interesting public can view.
