An article published in “The Astrophysical Journal” reports a study of the star Betelgeuse that concludes that it’s smaller and closer to Earth compared to previous measurements. A team of researchers led by Dr. Meridith Joyce of the Australian National University (ANU) used observations conducted using the Coriolis satellite’s SMEI instrument before it started dimming and three different modeling methods to conclude that its radius is about 764 times the Sun’s, its mass is between 16.5 and 19 times the Sun’s and its distance is about 548 light-years from the Earth.
