Starry Sky Blockbuster coming soon! Venus on the evening of the 8th

Original title: 8 days during the day moon to cover Venus, night Venus full moon

On November 8, "Taibai" joined hands with "Chang'e" to bring wonderful performances to the public. A lunar occultation of Venus will occur during the day and a conjunction of Venus will be staged at night.

Lunar occultation venus refers to the moon moving between the earth and Venus, the three in a straight line, at which time the moon will "pass" in front of Venus. Since the apparent diameter of the Moon is much larger than the apparent diameter of Venus, Venus is completely blocked when "passing by".

"The principle of the moon obscuring Venus is similar to that of a solar eclipse, but the visual effect will be much worse. When a solar eclipse occurs, the moon will cover the sun a little bit and then move away little by little; when the moon occult Venus occurs, Venus will completely disappear in a short period of time, and then quickly appear again after a while. Xiu Lipeng, director of the Tianjin Astronomical Society and an expert in astronomical science popularization, said.

Venus is the close neighbor of the earth, which was called "too white" in ancient China. When it appears in the morning, people call it "daystar" or "morning star"; when it appears at dusk, people call it "Chang Gung Star" or "Evening Star". Typically, Venus is the brightest object of the day except the Sun and Moon, with a maximum brightness of -4.9 magnitudes. Therefore, the lunar occultation of Venus is very ornamental in the "occultation" of the celestial phenomenon.

"This lunar occultation of Venus can be seen in the northeast region of China, the Korean Peninsula, and japan, but it happened during the day. Specific to the northeast region of Our country is at noon, because the sky is very bright, observation is very difficult, the need to use binoculars or small astronomical telescopes, but fortunately can be based on the moon as a reference to find Venus. As far as China is concerned, the middle and high latitudes outside the masking belt will see the picture of 'golden teeth' and 'crescent' passing by. It should be noted that when observing, you must be very careful to avoid the sun, otherwise it is easy to cause eye damage and damage to the observation instrument. If you are not sure, do not observe Venus during the day. Xiu Lipeng said.

If the weather is good, in the evening of the same day, the public in various parts of our country can also see the Venus moon with a very close angle. "At night, looking towards the southwest sky, one can see the crooked moth eyebrow moon on the fourth day of the tenth month of the lunar calendar, accompanied by Venus not far from the lower right. The two brightest celestial bodies in the night sky are nestled next to each other, which is particularly striking in the fading night sky, which is very graphic. Although Venus and the moon are not a very rare celestial phenomenon, the angles are as close as this time it is still worth seeing. Xiu Lipeng said.
