Arabia weather NASA’s Hubble Telescope has identified a giant comet with a nucleus 50 times larger than usual, heading toward Earth at 22,000 miles per hour (regarding 35,000 km/h), larger than any comet astronomers have seen before.
The comet’s ice core has a mass of regarding 500 trillion tons and a width of 85 miles (137 km), larger than the US state of Rhode Island.
The comet was first observed in 2010, but only now has the Hubble telescope confirmed its huge size. Scientists have long suspected the comet’s massiveness because it was so bright from a great distance, and now they have been able to confirm it.
(Hubble Space Telescope takes a picture of a comet’s nucleus on January 8, 2022, astronomers have come to an accurate measurement of the size of the nucleus, which is no small feat from a distance of regarding two billion miles)

The comet, named Bernardinelli-Bernstein (C/2014 UN271 (Bernardinelli-Bernstein)), has been in an elliptical (elliptical) orbit for three million years, putting it away from the Sun by regarding half a light-year.
The comet is now located less than two billion miles from the sun, as it approaches almost perpendicular to the plane of our solar system, and the closest point it will reach will be within a billion miles from the sun, and that will not be until 2031, following which it will return to the Oort cloud. Cloud), a huge reservoir of distant comets that surround the Solar System, extending many billions of miles into space.
and comets They are solid bodies consisting of ice and rocks, often called “cosmic snowballs”, and they were found from the remains of the period of the formation of planets, and came out of our solar system under the influence of gravity between the huge planets, and settled in the Oort cloud, and these bodies revolve around the sun, and when they approach more From it, it heats up and two tails begin to extend behind it. The first is made of gas and dust, and the second is made up of electrically charged gas molecules or ions, which is the ionic tail.
