NASA verified that the biggest comet ever detected has a diameter of around 85 miles and is now officially the largest comet ever spotted after Hubble Space Telescope studies. C/2014 UN271 (Bernardinelli-Bernstein (BB) was discovered in 2014 by two astronomers, Pedro Bernardinelli and Gary Bernstein, using Dark Energy Survey archived pictures. BB’s diameter was previously estimated to be between 62 and 124 miles, but NASA has officially verified the comet’s nucleus diameter to be 85 miles wide using the Hubble Space Telescope. According to NASA’s blog, BB has surpassed the previous record-holder comet C/2002 VQ94, which has an approximate nucleus diameter of 85 miles. The space agency adds that the comet has been hurtling toward Earth for a million years and will pose no danger to the planet when it reaches its closest approach in 2031, coming within a billion miles of Earth or around the distance between Earth and Saturn. Consider that if the whole area of BB...
