There are 88 officially recognized constellations in the night sky, which are divided into different categories based on their positions and historical significance. Here is a detailed explanation:

1. Northern Hemisphere Constellations

- Arctic Constellations: These include smaller constellations like Draco, Ursa Minor, and others that are visible from the northern hemisphere.

- Zodiac Constellations: Twelve constellations along the ecliptic plane, such as Aries, Taurus, and Gemini, which are associated with the traditional Western zodiac.

- Non-Zodiac Constellations: These include constellations like Orion, Canis Major, and Cassiopeia, which are also located in the northern sky but not part of the zodiac.

2. Southern Hemisphere Constellations

- Notable Constellations: In the southern sky, there are constellations like Centaurus, Crux (the Southern Cross), and Hydra. These are prominently visible from the southern hemisphere.

3. Equatorial Constellations

- Crossing the Celestial Equator: Some constellations straddle the celestial equator, making them visible from both hemispheres. Examples include Equuleus (the colic horse) and Eridanus (the river).

4. Lost Constellations

- Historical Mention: There are several constellations that were once recognized but are no longer in use. For example, the constellation Argo Navis was split into three separate constellations: Carina, Puppis, and Vela.

5. Modern Additions

- Recent Constellations: The International Astronomical Union has added modern constellations to fill gaps left by ancient star maps, especially in the southern sky. Examples include Norma and Dorado.

In conclusion, the 88 constellations are categorized based on their location relative to the equator and their historical recognition. These divisions help astronomers and enthusiasts alike navigate and understand the complex patterns of stars in the night sky.
