星群

pattern of stars recognized on Earth's night sky

AI overview

An asterism is a pattern of stars that people recognize when looking at the night sky, like the Big Dipper or the Summer Triangle. These star patterns help people navigate and find their way around the sky, even though the stars that make them up aren't necessarily related to each other or part of the same official constellation.

星群是天文學中出現在地球的星空中一種非正式星座型態的恆星集團。像星座一樣，它們基本上是由一些在相同方向上的恆星組成，但沒有物理上的實質關聯性，經常在與地球的距離上有著顯著的不同。一個星群可以由同一個星座的恆星組成，也可以是來自多個不同星座的恆星。它們主要由簡單的形狀或少數的恆星構成，使它們的樣式很容易辨認，因此對正在學習辨認星座與在觀看夜空的初學者特別有用。
