Constellations and Constellation Lines
星座にまつわるエトセトラ 「星座と星座線」
Currently, there are 88 constellations recognized worldwide. This standardization traces back to confusion that began in the Age of Discovery from the 15th century, when many people independently created southern-hemisphere constellations, making the situation unmanageable and prompting the 1922 decision to fix the list at 88.
