Closest approach to Earth on October 12 this year
It is the best time to observe it
Entering late October
The comet's brightness decreases somewhat
In good weather conditions
It can also be observed
But as it gradually moves away from the sun and the earth
The brightness gradually decreases
It will be difficult to see with the naked eye from November

Purple Mountain-Atlas Comet
It is a non-periodic comet
The track is a special oval
It takes about 61,751 years to complete one orbit around the sun
You only get a chance to see it once every 60,000 years
Did you see that?
Cosmic "conspicuous bag"
What the hell is going on?
The comet, named after the Chinese Astronomical Observatory - Comet Purple Mountain-Atlas (international number C/2023 A3), was first observed by the Purple Mountain Observatory of the Chinese Academy of Sciences on January 9, 2023, and is a comet with a yellow comet tail.
Huiwei small science
As it approaches the Sun, the temperature rises due to increased radiation, and the comet's material sublimates, forming hazy coma and a tail of thin material around the comet's nucleus, resembling a broomstick. The tail of a comet can be divided into ionic tails, which are usually blue in color, and dust tails, which are determined by the sunlight reflected by the dust.

The brightness of a comet depends on two factors, one is how close it is to the Sun, the closer it is to the Sun, the brighter it will shine; The other is how close it is to the Earth, and the closer it is to the Earth, the brighter we see.
Astronomical experts say that the first two days should have been the brightest time for Comet Purple Mountain-Atlas, but unfortunately because it is in the same direction as the sun, its light is completely drowned out by the sun.
Over the next two weeks, it gets farther and farther away from the sun, and it is possible to see it in the evening after the sun sets, with the help of some equipment, in the same direction as the sun sets.
