The brightest stars in the sky are those that include stars and planets in turn.

First place: Sun (No objection. -26.7 and so on. )

Second place: the moon (basically the time to see the moon is-10, and the full moon can be-12.6, etc. )

Put the planet in the past first. Changes are more complicated. Let's talk about stars first.

The first star: Sirius (-1.47, etc. )

Second place: Canopus

Third place: South Gate

I can't carry it from now on. There are 2 1 brightest stars in the sky, which can definitely be seen in cities with serious light pollution.

Spring: Xuanyuan XIV, making great friends and making friends with plain clothes.

Summer: Hegu II (Altair), Vega I (Vega), Tianjin IV, Antares II.

Autumn: Shimen, Beiluo

Winter: Pistachio, Capella, Betelgeuse, Betelgeuse, Beihe III, Nanhe III, Sirius.

Only 15 first-class stars are listed above, and there are still 6? Those six stars are too far south to be seen in the mid-latitude area of the northern hemisphere, and even if they are seen, the altitude angle is pitifully low. In fact, Shanghai can see two of the six, and I have never seen any of them in my 20 years of life (orz).

After talking about first-class stars, there are second-class stars with less brightness. There are about 40 stars in the sky. I may be able to list them one by one, but it's meaningless. I believe that the brightness of second-class stars can be easily seen in cities as long as they are slightly better. For example, there are six second-class stars in the Big Dipper, which can be found on the road, but only if you know where to look again ... but a little secluded place is definitely no problem.

Then there's a third-rate star. There are about 200 third-class stars. My ability is limited, so I can't list them all. Seeing them in the city requires a little effort to adapt the naked eye to the darkness, and then find a place that can block most of the light. I should be able to find them. I want to watch the meteor shower again. If I can't find the third star, I'll go straight to sleep.

Then there are four-star stars. Seeing them in a big city like Shanghai where I live depends on my personality. Occasionally, when the weather is fine near my home, you can see four-star stars, and there are about seven or eight hundred in the sky.

Five or six stars are dark stars. It is almost impossible to see them in the city. If you can see five or six stars, I believe the Milky Way in summer and autumn is not a problem. There are more than six thousand five or six stars in the sky. These stars are important signs when looking for celestial bodies with binoculars, but they are not easy to see at ordinary times. In Shanghai where I live, it is difficult to meet them without running 200 kilometers.

There are more stars invisible to the naked eye. These stars need a telescope to see. Most of these stars have not seen it with them, nor for some specific purpose. It's no use looking at them. I can only say sorry to them here.

Look at this planet again:

The brightest is Venus, which is always above -3 when seen, but it can only be seen near the sun.

Then Jupiter, the brightest is -2.6, and the darkest is-1.4.

Mars is particularly unstable, the brightest is -2.4, and now it is only about 2.

The brightness of Saturn hovers between 0.2- 1.0, and so on.

And mercury. When you can see it, the brightness is always around 0, but it is too close to the sun. August 1 1, close to the western distance of Mars. When observing the Perseid meteor shower, you tried to find him, but the dust in Shanghai was so strong that you seemed to see it again, so you could only doubt it. You know, Mr. Copernicus has never seen mercury in his life.

The brightness of Uranus is around 5.9, which is almost invisible to the naked eye, but it cannot be distinguished when it is seen, but it should not be difficult to find it with a telescope. I also tried to find it in August 1 1, and it was done in 5 minutes.

Neptune's brightness is 8-9, so it is invisible to the naked eye. Although I have seen it, I actually came to see it myself after others found it. Challenge yourself in the future.
