Current calculations estimate that the Betelbuddy has a mass of 1.17 times that of the Sun and orbits Betelgeuse at a distance 2.43 times the star’s radius, equivalent to roughly 1850 solar radii.

so could Betelgeuse, but on a different scale. NASA’s Hubble Space Telescope appeared to confirm that a “burp” from within Betelguse produced a mass ejection of material that became a dust ...
