The biggest comet ever seen has a core ‘blacker than coal’, and it’s heading like this

Astronomers have measured the icy core of one of the largest comets ever discovered – a 4-billion-year-old giant rock currently heading toward Land at 22,000 mph (35,000 km/h).

Don’t worry: The massive icy rock — named C/2014 UN271, or Bernardinelli-Bernstein (BB) after its discoverers — is on track to miss our planet by about a billion miles as it approaches its closest point in 2031, Live Science previously reported. For comparison, this is greater than the average distance between Saturn and the sun – And far enough away that stargazers wouldn’t be able to see the BB’s flight with the naked eye.
