Let the impossible scale of the universe carry you into sleep. The largest known star is Stephenson 2-18, a red supergiant over 2,150 times wider than our Sun . UY Scuti, once thought the record-holder, is now measured at around 1,700 solar radii—still large enough to swallow Jupiter's orbit . In the Large Magellanic Cloud, WOH G64 and WOH S170 each exceed 1,400 solar radii . A peaceful reminder of our beautiful insignificance.
