Nearest constellation-the constellation closest to the earth

What constellations are there in the Milky Way? The constellation closest to the earth is the zodiac. Are the twelve constellations in the Milky Way?

1922 The General Assembly of the International Astronomical Union decided to divide the sky into 88 constellations. 1928 officially announced the names of 88 constellations and divided the sky into three sky regions, 29 constellations in the northern hemisphere and 47 constellations in the southern hemisphere. 12.

Orion is closest to the earth.

Images of constellations are projected. There is a concept in astronomy called celestial sphere, which is an imaginary concept. Because we can't grasp the distance between stars and us when looking up at the starry sky, the relative position between stars is nothing more than the intersection of the line between stars and the center of the earth and the celestial sphere, that is, the projection on the celestial sphere. Therefore, the projection positions of two stars far apart in the universe on the celestial sphere may be very close, thus forming a constellation.

The ecliptic is a hypothetical tool.

Yes, not only the stars of the zodiac, but all the stars we can see with the naked eye are in the Milky Way. Then explain a concept to LZ. The so-called constellations don't really exist in physics. Constellation is that people divide their starry friends into several areas (there are 88 in the whole day) in order to recognize the stars. Zodiac constellation 12 is just the scattered 12 region on the ecliptic. Two seemingly close stars may actually be far apart, but there is no doubt that these stars belong to the Milky Way (the Milky Way is a real complex group of stars).

The zodiac is the mapping image of the cosmic cluster on the celestial sphere. Just like the plane and elevation in the design, it is only the projection of things.

The constellation closest to the earth has not been explained yet, but is located in proxima centauri Centauri, scientific name: Alpha Centauri C, only 4.22 light years away from the sun. Because the constellations are only in one place from the earth, they are not necessarily together, so we can't say "nearest"
