Such refinements in the images of Betelgeuse's atmosphere has been helping to resolve the mystery of how massive amounts of dust and gas are expelled from red supergiant stars, an important source of enrichment for the interstellar medium.
Distance in miles = 3.15 times 10 to the 15th power. That is 315 followed by 13 more zeros! We are 527 light years (a light year is how far light can travel in one year) from Betelgeuse. Each light year is 5.98 trillion miles (10 to the 12th power). Source(s): Just memorized the distance in light years and multiplied by 5.98 trillion. Doug H Â· 7 years ago.
