devir
Sign in to savezamanla değişen bazı astronomik miktarlar için referans noktası olarak kullanılan an
An epoch is a specific moment in time that astronomers use as a reference point to measure how celestial objects move and change over time. It matters because the positions and motions of stars and planets shift slightly, so scientists need a fixed starting date to accurately track and predict where these objects will be in the sky.
