黑暗有多少个星座呢英文

The number of constellations in the night sky is not fixed, as it varies depending on the observer's location and the time of year. However, there are approximately 88 constellations visible to the naked eye, which can be divided into two main groups: the Pleiades and the Orionids.

The Pleiades group consists of seven constellations that are easily recognizable by their bright stars. These include the Pleiades, Cygnus, Hydra, Orion, Cassiopeia, Perseus, and Scorpius. The Pleiades group is named after the Greek mythological figure Peleus, who was said to have built a ship with his son Atlas to rescue his wife Thetis from the sea monster Chimera.

The Orionids group consists of 12 constellations that are also easy to spot. These include Orion, Alnitak, Taurus, Arcturus, Ursa Minor, Ursa Major, Bootes, Cassiopeia, Cygnus, Cygni, Leo, and Canis Major. The Orionids group is named after the ancient Greek hunter Orion, who was known for his distinctive bow and arrow.

In addition to these two groups, there are several other constellations that are difficult to spot but still worth mentioning. These include the Hyades, Sagittarius, Aquarius, Gemini, Cepheus, and Capella.

Overall, there are around 90 constellations visible to the naked eye, which can be divided into three main groups: the Pleiades, Orionids, and other constellations.
