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
If placed at the center of our solar system, it would engulf the orbits of Mercury, Venus, Earth, and Mars, likely extending past Jupiter's orbit . alpha orionis
Usually the 10th brightest star in the night sky, its magnitude typically ranges from +0.0 to +1.3 . Recent studies suggest the existence of a smaller,

Despite being only about 8 to 10 million years old —much younger than our 4.6-billion-year-old Sun—its massive size caused it to evolve rapidly.
(α Orionis), famously known as Betelgeuse , is a massive red supergiant marking the western shoulder of the constellation Orion . It is one of the largest and most luminous stars visible to the naked eye. Physical Characteristics
