Recent studies suggest the existence of a smaller, Sun-like companion star (Betelgeuse B) that may influence its long-term brightness cycles. Life Cycle and Future Usually the 10th brightest star in the night

In late 2019 and early 2020, it experienced a historic drop in brightness, eventually attributed to a massive surface mass ejection that cooled into an obscuring dust cloud. famously known as Betelgeuse

Betelgeuse is a , meaning its brightness fluctuates over time.
