Experts explained that Jupiter rushing the sun refers to Jupiter, the earth and the sun in turn into a straight line. During Jupiter's rush, Jupiter is closest to the earth, with the largest diameter and the brightest.

According to reports, this year's Jupiter rushes, China and even all over the world have the opportunity to watch. From September 24th to 30th, in the early morning (22:00 to 2:00 the next day), Jupiter radiated the charming light over the earth equator, becoming the brightest celestial body in the night sky (the sun, the moon, and Venus are all in Below horizon). The public living in the Earth's equatorial public can see Jupiter above his head.

Because Jupiter's running around the sun is an oval shape, its eccentricity rate is 0.0486, which is larger than the eccentricity of the earth's orbital 0.0167. Jupiter's rotation cycle is 11.862 years, so in about 12 years, Jupiter will run to the closest place to the sun, that is, Jupiter's recent point. If Jupiter's time is near nearby, Jupiter will be closest to the earth, and Jupiter's viewing will reach great. On January 21 next year, Jupiter has reached the recent point. Therefore, this time Jupiter is closest to the earth from the earth, only about 591.3 billion kilometers, the diameter of the view is 49.88 cents, and the viewing level has reached 2.9 stars. It is the brightest since October 3, 1951 (Jupiter Chong Sun). The next time Jupiter is closer and brighter from the earth, waiting for 107 years, that is, wait until October 7, 2129 (Jupiter Chong Sun).

Experts say that the best time to observe Jupiter is in the sky. At this time, Jupiter is in the direction of the south and becomes a veritable "compass", and it is the largest height and the highest level of the atmosphere through the starlight, and it is the easiest to observe and shoot. In Guangzhou, Jupiter's time: September 27 is 0:16 (horizontal height 67 degrees); October 7th is 23:32; October 17th is 22:48; October 27th It was 22:05. Recently, Jupiter around the world is about 4.4 minutes earlier every day than the previous day.
