First-order star constellation

Many times we will look at the horoscope of the first-class star. The zodiac is closely related to the movement of the sun. This constellation itself is full of imagination. Looking at the horoscope more can avoid some troubles. After reading the horoscope of the first-class star, quickly transfer it to the people around you.

The first-class star constellation 2 has 2 1 first-class stars all day.

Upstairs, I take the liberty to point out that there are only 2 1 star, and there is no 22nd star.

There is a difference between bright stars and dark stars. Obviously, there are more bright stars than dark stars. In order to express the brightness of stars, people use "magnitude" to classify all-day stars: the darkest star visible to the naked eye is 6, the star brighter than 6 is 5, the brightest star is 4, and the brightest star is 1.

Magnitude 1 is about 2.5 times brighter than magnitude 2 and 6.2 times brighter than magnitude 3.

Altair is 1. Vega is brighter than Altair, with a rating of 0. Stars brighter than 0 are-1, -2, etc. Sirius is the brightest star in the whole sky, with a magnitude of-1.6, etc.

On the other hand, stars that are darker than 6 are 7, 8, 9 ... They must observe with a telescope. The larger the aperture of the telescope objective, the darker the star can be observed. At present, the largest telescope in the world can observe dark objects such as 24 ~ 25.

After measuring the magnitude of each star in the sky, the number of stars in a certain magnitude range can be counted. For example, we classify stars larger than 1.5 as "1", 1.6 ~ 2.4 as "second-class stars" and 2.5 ~ 3.4 as "third-class stars".

The ratios in the table are approximate. Generally speaking, the smaller the order of magnitude, the smaller the proportion.

Generally speaking, people with naked eye vision 1.5 can see the darkest stars close to 6.5. This can only be achieved on the mountains far away from the city lights and the sky is completely dark.

According to legend, the ancient Greeks liked Pachas and first divided the luminosity of the stars in the sky into six grades. The brightest is 1, the second brightest is 2, and the darkest is 6. This method is rough. Later, someone subdivided each magnitude into 10 or 100, etc. In this way, the order of magnitude has a decimal. For example, the magnitude of Altair on the east bank of the Milky Way (Tianhe) is 0.77. If rounded to one decimal place, it is 0.8, and so on. , and then simply put, it is 1.

If a star is brighter than Altair, its magnitude is 0. 0 originally means "no", but it means "yes" in magnitude, which is brighter than 1 For example, Vega on the west coast of the Milky Way is a 0-magnitude star.

There are many stars brighter than Vega in the sky. Are they child stars? Astronomers came up with the idea of putting a "-"before a number (read negative here). For example, the magnitude of Sirius is-1.6. At night, except the moon, the brightest star in the whole day is Venus, and the magnitude at the brightest time is -4.5. Look, isn't that strange? The bigger the negative number, the brighter the star. According to this method, the magnitude of the full moon is-16 and that of the sun is -27.

Stars darker than magnitude 6, their magnitudes are 7, 8, etc. , they are arranged downwards in turn. This kind of star can only be observed with a telescope. At present, China's largest astronomical telescope (aperture 2. 16m, installed at Xinglong Observatory of Beijing Observatory) can observe 19 stars. The world's largest telescope (6 meters in diameter, installed on the Caucasus Mountain) can observe 22-magnitude stars.

It shows the brightness of the stars that we feel with our naked eyes. The same star looks brighter when it is near us. Stay away from us, it will look dim.
