What is the 48 constellations defined by Ptolemy?

Andromeda | Aquarius | Aquarius | Sagittarius | Aries | Auriga | Shepherd | Cancer | Canis | Capricorn | Cassiopeia | Centauri | Cepheus | Corona | Crow | Big Jazz | Cygnus | Dolphin Gemini | Ophiuchus | Leo | Scorpio | Libra | Sirius |

Sailing south-divided into base, stern and sail.

Ophiuchus-actually it intersects with the zodiac, but traditionally it is not considered as one of the zodiac constellations.

Later, the number of constellations kept increasing, mainly to fill the gap between Ptolemaic constellations (because the ancient Greeks thought there was a dim gap between bright constellations), and another reason was that when European explorers drove south, they could see some stars that they could not see before, so they had to join new constellations to fill the southern sky. The 38 newer constellations are:

Pump seat

Celestial constellation

Carving seat

Lubao

Dog dog

Diptera constellation

Compass seat

Tiange constellation

Late constellation-actually a traditional constellation.

Southern cross constellation

swordfish

Celestial furnace

Crane constellation

Watch factory

Aquarius constellation

Indian chair

Tokage constellation

Little lion constellation

Tmall constellation

Shannan building

(of a microscope) base

Kirin constellation

Flying seat

Rectangular ruler seat

Antarctic constellation

Peacock constellation

phoenix

Frame seat

Compass seat

Net seat

Yu fuzuo

Shielding seat

sextant

Telescope base

Southern triangle

azalea

Flying fish constellation

Fox constellation

Some nominated constellations were not adopted as official constellations in the end. The famous one is Quadrans Muralis (now part of Capricorn), and the meteor shower is named after it. There are also some less formal star arrangements called constellations, such as Beidou.

In fact, the stars in the same constellation are irrelevant in most cases. They are only in the same line of sight, but in fact they may be far apart-if we were in another solar system of the Milky Way, the starry sky we saw would be completely different.

Because there are many stars in the sky, most of them are stars (the position in the sky has not changed much), and about 6000 stars can be seen by the naked eye. In order to facilitate the memory and study of the starry sky, the Babylonians divided the sky into many regions called "constellations", and each constellation was marked by the special distribution of bright stars.

Around 270 BC, the ancient Greeks divided the visible sky into 48 constellations, connected the main bright stars in the constellations with imaginary lines, and imagined them as people or animals, and gave them appropriate names in combination with fairy tales. This is the origin of the constellation name. Because there are more than forty constellations in Greek mythology living in the northern sky and north and south of the equator, they are just our common constellations. As long as you remember the positions and names of these constellations and their relationships with other constellations around you, and remember the imaginary pictures connecting the main bright stars, you can easily identify the whole starry sky.
