What, uh, what constellation _ what constellation?

What constellations are there in 1- 12?

1, Aquarius (1.20 ~ 2.5438+08)

Aquarius is a big but dark constellation, located between Capricorn and Pisces in the zodiac. There are flying horses, ponies, dolphins and eagles in the northeast and Pisces in the southwest. Extend the beta and alpha stars of Pegasus to the south by one and a half times, and there will be a dark star. A large dark star here constitutes Aquarius. Although Aquarius is the zodiac (in the zodiac, Aquarius is also called "Aquarius"), there are no bright stars in it, and the brightest one is only 3m.

2. Pisces (2. 19~3.20)

Pisces, one of the twelve constellations, covers an area of 889.42 square degrees, accounting for 2. 156% of the whole day, ranking 14 among the 88 constellations in the whole day. This constellation has a messier objects: M74, which is located near the second right of the brightest star in Pisces. On the celestial sphere, there are two intersections between the ecliptic and the celestial equator. The intersection formed by the intersection of the ecliptic from the south of the celestial equator from west to east and the north of the celestial equator is called the "vernal equinox" in astronomy, which is of great significance in astronomy.

3. Aries (3.2 1~4.20)

Aries is the first sign of the zodiac, located in the southwest of Taurus and east of Pisces. Every year from June 5438 to mid-February at 8: 00, Aries is above our heads. The four stars Pegasus and Andromeda in the autumn sky make up a big box. Draw a straight line from the two stars in the north of the box and extend it to the east for one and a half times, and you can see Aries.

The two brightest stars are the two horns of Aries. Although Aries is unremarkable, it is also the zodiac, so its position in astronomy is still very important. The vernal equinox was in Aries before 2000, and now it has moved to Pisces.

4. Taurus (4.2 1~5.20)

Taurus, with an area of 797.25 square degrees, accounts for 1.933% of the total area of the whole day, ranking 17 among 88 constellations in the whole day. The bright stars of Taurus Pisces are arranged in a V-shaped structure, also known as Taurus V-shaped. Among them, the orange-red Pisces is one of the few 0-magnitude stars in the sky, just like the North River in Gemini and Capella in Auriga.

Nanhe III in Canis minor, Sirius in Canis major and Betelgeuse in Orion form a winter hexagon. The most famous celestial body in Taurus is "two clusters plus a nebula". After connecting Orion γ and Epicurus, the distance to the northwest has doubled, and there is a famous open cluster-the Pleiades.

5. Gemini (5.2 1~6.2 1)

Gemini, one of the zodiac signs, has Taurus in the west and Cancer in the east. Auriga and the very humble Tmall are located in the north, while unicorns and Canis canis are located in the south. Gemini has two very bright stars-Beihe III and Beihe II. Other stars are dark, and only γ can be seen under the city lights;

But far away from light pollution, thin galaxies can be seen passing through the west of Gemini. The winter hexagon consists of three rivers in the north, five rivers in Taurus, two rivers in Auriga, three rivers in the south of Canis, Sirius in Canis and Betelgeuse in Orion.

6. Cancer (6.22~7.22)

Cancer, one of the zodiac signs, is composed of three bright stars, α, β and δ, forming a herringbone structure. Cancer is to the west of Leo and to the north of Ophiuchus. Although it is the darkest of the zodiac signs, it contains the fascinating M44 nebula. For astronomy lovers, Cancer is dark, but it is very attractive.

Many interesting and unique stars will be found after observation. Near the Delta Star in the center of Cancer (or between the two bright stars of Leo Xuanyuan XIV and Gemini Beta), people with good eyesight can see a small white fog, which was called "corpse gas" in ancient China.

7. Leo (7.23~8.22)

Leo, one of the zodiac signs, covers an area of 946.96 square degrees, accounting for 2.296% of the whole day, ranking 12 among 88 constellations in the whole day.

Every spring, shortly after the sun goes down, it is on the horizon in the east, and Virgo always shines in the night sky in spring and summer. The apparent magnitude is 0.98. Every April 1 1 day, the virgo center passes above the transit. The modern autumnal equinox is located near Right Law Enforcement (Virgo β).

9. Libra (9.23~ 10.23)

Libra is one of the zodiac signs and one of the Ptolemaic constellations. Between Virgo and Scorpio, there are more than a dozen galaxies in this constellation that can be seen with 8-inch or larger telescopes. The four brightest stars in the constellation, α, β, γ and σ form a quadrilateral, and β and the spring triangle form a big diamond. Libra beta, whose middle name is "zubeneschamali", is the only star with green visible to the naked eye all day. Libra alpha star "zubenelgenubi" is a binary star, which is composed of α 1 with brightness of 5.2 and α2 with brightness of 2.8, and appears blue and white.

10, Scorpio (10.24 ~11.21)

In addition, it is also a zodiac, so it is particularly eye-catching.
