What is the conjunction of Jupiter and the moon?

The conjunction of Jupiter and the moon means that Jupiter and the moon just run to the same longitude, and the distance between them reaches the nearest astronomical phenomenon. Jupiter's conjunction with the moon is one of the phenomena of planetary conjunction with the moon. The phenomenon of planets merging with the moon will happen dozens of times in a year. Because Jupiter is relatively large, in addition to Venus and the moon, "Jupiter and the moon" is one of the best viewing effects.

Jupiter is the king of planets in the solar system? [2] Among the eight planets, it has the largest volume and mass and the largest number of satellites, so it is called "giant planet". It is said that such a behemoth should be dazzling in the sky, but in fact, because Jupiter itself does not shine, people can only see the sunlight reflected by it, so the brightness of Jupiter is very different from that of Venus. The weight of Jupiter is more than 2.5 times that of the other seven planets combined and 3 18 times that of the earth. According to the distance from the sun, Jupiter ranks fifth. Jupiter has been bright and suitable for observation since 20 10 and 10.

Because the period of the moon's revolution around the earth is about 27 days, it will be close to several planets in a period of revolution. If the stars and the moon are exactly equal to the longitude of the Yellow River at a certain moment, it is said that the stars and the moon are consistent. Of course, the diameter of the moon's apparent circle is about half a degree, and sometimes it even blocks distant planets or stars, forming a lunar occultation. It is rare to see the moon with good observation conditions, but bright stars and the moon are often staged.

Following the conjunction of Saturn, Venus and Mars, this month's star-studded "Romantic Series" continued to be staged brilliantly on the 27th. This time, the "hero" was replaced by the "giant" Jupiter of the solar system. Astronomical experts said that if the weather is fine, interested citizens and early risers can enjoy this romantic "moonlight express" before dawn.

The astronomical scene of "Jupiter and the Moon" previously shot over Zhengzhou, Henan Province, was photographed by Xinhua News Agency reporter Zhu Xiang.

When the planet meets the moon, the moon and the planet are very close in vision, which is a very distinctive astronomical phenomenon for both viewing and photography. In particular, the combination of Venus and Jupiter, the two brightest planets, is favored by fans.

Astronomical data show that Jupiter was in Ophiuchus all March, and the rising time was advanced to 1: 35 the next day. At sunrise, the sky changes from the southeast to the southwest, and the brightness is -2. 1 etc. This is visible in the middle of the night.

Zhao Zhi Heng, an expert in astronomy education and director of Tianjin Astronomical Society, said that at 5 o'clock on the 27th, the moon hung in the southwest sky like a straight bowstring, glittering and translucent, with milky light. Not far from the lower left of the moon, there is a bright star, which is Jupiter. At this moment, in the slight dawn before dawn, the stars and the moon are bright, full of glory and picturesque. As the sky brightened, Jupiter was gradually submerged by the sunrise, leaving the moon to meet the sunrise alone.

"Conditional public can try to shoot the wonderful performance of Jupiter's full moon with the help of a medium telephoto lens, or try to observe Jupiter's colored stripes and shrinking red spots with a simple astronomical telescope." Zhao Zhi Heng warned.

According to experts, in fact, the combination of the planet and the moon is not uncommon, and it will happen dozens of times a year. Jupiter, with its relatively large volume and numerous satellites, is one of the most easily observed celestial bodies with the naked eye. Therefore, in addition to "Venus combined with the moon", "Jupiter combined with the moon" is also the best planet combined with the moon.

Venus and Jupiter's "two-person turn" appeared in Tianyu, staged a "stars attract each other" drama.

Zhao Zhi Heng, a member of the Chinese Astronomical Society and director of the Tianjin Astronomical Society, said that on the morning of June 22, 65438, before sunrise, Venus, which appeared as the "morning star", was embedded in the blue sky like a gem, and not far below Venus, there was a bright star shining, that is Jupiter. Venus is bright, Jupiter is soft, and the two stars compete for beauty, which is extremely romantic. "However, this astronomical drama will not last long. As time goes by, the sky is getting brighter and brighter, and Venus and Jupiter will fade out of the sky one after another. "

Venus and Jupiter are just a visual phenomenon. Astronomical experts explained that Venus and Jupiter are about 780 million kilometers apart, which is equivalent to 5.2 times the distance between the earth and the sun. Their meeting was just a close sight, not a real close.

"Venus and Jupiter, two big planets, get together from time to time and have a lot to watch." Zhao Zhi Heng reminded, "Because there are no other bright celestial bodies around, the two stars get together and the picture of Qiyao Tianyu is very clear, which becomes a beautiful landscape on the horizon."

"Mars and the Moon" staged "Moonlight Express" to dress up Tianyu.

"In February this year, Mars went from Pisces to Aries and was in the southwest sky at sunset. It fell at about 23: 12, and the brightness was 1.0, which was visible in the first half of the night. " Zhao Zhi Heng, an expert in astronomy education and director of the Tianjin Literature Society, said that 1 1 is behind the sun, and the "first quarter moon" on the seventh day of the first lunar month hangs in the southwest sky. Not far from the right side of the moon, there is a red star, which is Mars. "Red Mars and the bright moon, facing each other affectionately in the sky, staged the' Moonlight Express', adding a bit of interest to the night sky in early spring."

Zhao Zhi Heng suggested that Mars is the only Earth-like planet that can be clearly seen with a telescope. Interested citizens use small astronomical telescopes to observe "Mars and the Moon", and the effect is better. "Through the telescope, Mars looks like an orange-red sphere, which is very beautiful."
