NASA: The universe is filled with spectacular mysteries and astronomers have found yet another one to puzzle everyone’s mind. Recently an interstellar comet has been discovered and it is the largest one ever discovered. But not only is its size surprising but also how old it is. The ancient comet is expected to be at least 4 billion years old. That means, the comet is almost as old as our Earth. But the piece of information that makes this comet truly scary is that it is headed towards Earth. So, how likely is a comet strike on the Earth? And what makes this comet so intriguing to the scientists? Read on to find out.
The comet, named C/2014 UN271, or Bernardinelli-Bernstein (BB) after the discoverers Pedro Bernardinelli and Gary Bernstein, was first spotted in October 2014. Right now the comet is traveling through the Oort cloud and is moving towards the Sun at an extremely high speed of 35,000 km/h. The comet is estimated to be around 128 kilometers wide, making it the largest comet ever spotted.
66 million years ago, the asteroid that made dinosaurs go extinct and brought on an ice age was about 10 kilometers wide. In comparison, if BB comet were to strike the Earth at its speed, the entire planet would explode without another chance for newer species to come again. The Earth as we know it would cease to exist. However, according to current projections by NASA, the comet is about to miss our planet by a humble distance of 1 billion miles when it makes the closest approach in 2031. For reference, that distance is greater than the distance between the Earth and Neptune.
However, these are current projections and the comet can change its direction anytime and that is why it is incredibly crucial for scientists to constantly
