Astronomers have measured the largest comet to date, its core 130 kilometers long – Space – Science and Technology

With the help of the Hubble Space Telescope, astronomers have measured the largest known comet, whose core is more than 130 kilometers long.

The American informed about it National Aeronautics and Space Administration (NASA). Comet Bernardinelli-Bernstein, also known as C / 2014 UN271, was discovered by scientists as early as 2010, but only now have they been able to calculate the size of a body moving on the edge of the solar system. It is about fifty times larger than most other known comets.

The giant comet moves at speeds of more than 35,000 kilometers per hour, but poses no threat to Earth. It will not approach the Sun more than a distance of about 1.5 billion kilometers, which is slightly more than the distance that the Sun separates from Saturn, and it will not happen until 2031.

“We always knew that this comet would be big because it is very bright, even though it moves at such a great distance. We’ve confirmed it now, “The Times quoted astronomer David Jewitt of the University of California as saying.



Comet Bernardinelli-Bernstein probably comes from the so-called Oort cloud. It is a cloud of about a trillion long-period comets, located about 7,500 to 15,000 billion kilometers from the Sun, and is probably the top layer of the solar system. The comet moves in an elliptical orbit, and one orbit around the Sun takes three million years. At its farthest point is about half a light-year from the Sun.
