Dubbed the “Christmas Comet,” the icy giant described as a massive, dirty snowball skimmed past the Sun at a distance of just 730,000 miles (1.17 million kilometers) around 1830 GMT on Thursday.

Most astronomers had predicted the comet, with an estimated diameter of some 0.75 miles (1.2 kilometers), would not survive the flypast.
Still, some observers had held out a sliver of hope that the 4.5 billion-year-old comet might have survived.
