Mercury is a great opportunity for mercury in the near future

After a long period of research, astronomical telescope manufacturers have discovered that the best viewing period of mercury has finally come! The orbit of the eight planets (the smallest circle is the orbit of mercury) from the earth, mercury is the closest (not more than 28) to the sun, and often annihilated in the sun's brilliance, so a few times a year, mercury is only a few times before and after the big time.

Mercury alloy star is the celestial phenomenon that mercury and Venus are located near the same yellow cross, which looks like mercury is very close to Venus. Mercury and Venus are the same terrestrial planets

(average density, solid surface, small size)

In March, there will be 2 astronomical images of mercury that coincide with Venus and the first in March 6th, but because Mercury is near the sun, the sun is affected by the sun, and the second mercury alloy star will occur in March 18th, because Mercury is far away from the sun in March 15th, and the altitude of mercury is more than 15 at sunset. The sun is slightly affected by the sunlight, and the observation condition is better than that in March 6th. When the second planet is mercury, mercury is about 4 degrees from Venus.

Time and place of observation

In Beijing, for example, the sunset of March 18th is 18:24, so that Mercury will emerge from the low level in the west after sunset (18:30).

The following 3 pictures show the gradual progress of mercury and Venus to the horizon after sunset, and less than 20 minutes, the height of Mercury's level dropped by 3 degrees.

At 18:42, mercury is located in the west, with a height of about 13 degrees, while Venus is located on the lower left side of mercury.

At 18:48, the altitude of mercury has dropped to about 12 degrees.

At 18:59, the altitude of mercury has dropped to about 10 degrees.

In addition, mercury was nowhere near the horizon at 19:30 or so. Considering that the height of the earth is very low, Mercury's light needs to pass through the thicker earth's atmosphere, the atmospheric extinction is seriously affected, and mercury is more gloomy than it is at the height of the earth, so it is not too long to see mercury after sunset. Cherish it!

I would like to remind you that watching mercury alloy stars can be seen with the naked eye without the aid of astronomical telescopes. If you want to see mercury and Venus at the same time, you need to have higher ground and wider Western horizons. Besides, the weather is fine, there is no cloud cover and so on. Even if not, it should be understood.

Why is mercury rare?

Mercury and Venus belong to the earth's interior planets, and their orbit is within the orbit of the earth. The characteristic of the earth's planets is that they always like to stay with the sun. From the perspective of the earth, the earth's planets and the sun will never exceed a certain angular distance. For mercury, it always likes to haunt the sun at no more than 28 degrees.
