A recent study reveals the details of a huge comet that is 100 times larger than the ordinary


A recent study revealed the details sinner Massive, 100 times larger than an ordinary comet, and it is among the ice globes farthest from the sun with an active stream of dust and gas around it, as astronomers analyzed satellite images of the comet, also known as C/2014 UN271, which was identified earlier this year. general.

According to the British newspaper, “Daily Mail”, the development of active comets Bernardinelli-Bernstein (BB) represented a thin envelope of vaporized ice and surrounding dust as it approached the sun, and the researchers found that BB ice is not water, but carbon monoxide, which is known on Earth to poison humans.

BB, named after its discoverers, has a diameter of 62 miles (100 kilometres), more than 100 times the diameter of an ordinary comet. Usually comets are no more than half a mile (one kilometer) in diameter.

It is called the largest comet found in recorded history, although some have suggested that Comet Sarabat, over 513,000 miles wide and observed during close approach in 1729, is the largest.

BB is also thought to have a mass at least a million times greater than that of ordinary comets, as well as a diameter of a hundred times greater.

BB is more than 1.8 billion miles (2.9 billion km) from Earth, but it is gradually approaching the center of the solar system. It has been inside the orbit of Neptune since March 2014, and it will pass inside the orbit of Uranus in December 2022.

The new study was conducted by researchers at the University of Maryland (UM) who said that BB is among the distant comets. The researchers did not actually specify the size in the new study, but they quoted the size as at least 100 km, as presented by Bernardinelli et al., in announcing their discovery. earlier this year.

Scientists first discovered Comet BB in June 2021 using data from the Dark Energy Survey, an international effort to survey the skies over the Southern Hemisphere.

The survey captured the comet’s bright core, but it didn’t have a high enough resolution to reveal the recently observed envelope of dust and vapor that forms when a comet becomes active.
