News from the Natural World: Large comet headed to earth causes somewhat of a dilemma in the animal kingdom. One of the largest comets ever seen by the animal kingdom is headed near earth. The comet is called Bernardinelli-Bernstein and is offering all animal astrologers the chance to see an object from the extreme edges of the solar system. The most recent estimates put the comet’s nucleus at about 150km wide. That’s over 125 Gazillion ants. That’s by far the biggest size estimate for a comet in decades. Over the next decade, Bernardinelli-Bernstein will continue to get brighter as it approaches the inner solar system, dive-bombing the plane of the planets’ orbits from below. It will make its closest approach on January 21, 2031, when the comet is expected to come within about a billion miles of the sun, slightly farther away than Saturn’s average distance. It will then begin its long retreat back into the solar system’s outer realms, remaining visible into at least the 2040s, if not decades longer.
