A comet the size of a US state is fast approaching the sun

A comet the size of a US state is fast approaching the sun

Select NASA’s Hubble Telescope Recently a giant comet with a nucleus 50 times larger than usual, is heading toward Earth at 22,000 mph (about 35,000 km/h), larger than any comet astronomers have seen. before. The comet’s icy core has a mass of about 500 trillion tons and a width of 85 miles (137 km), which is larger than the US state of Rhode Island.
According to (world-today), the team of NASA scientists confirmed this through analysis from the Hubble Telescope, the largest comet ever discovered. It is Bernardinelli-Bernstein, its core is about 500 billion tons in size and 137 kilometers wide. According to research published in Astrophysical Journal Letters, the core of this comet is 50 times larger than known comets. Meanwhile, its mass is 100,000 times greater than that of an ordinary comet closer to the Sun. Even if you approached the Earth at 35,000 kilometers per hour, you would be 1,600 million kilometers from the Sun, and that will happen in the year 2031. Knowing that there was the comet that astronomers Pedro Bernardinelli and Gary Bernstein discovered 10 years ago when he was working in the Cerro Doololo laboratory International Airport in Chile, it was 4.8 billion kilometers from the sun.

This comet is big because it is so bright at such a long distance, said David Govid, a professor of planetary sciences and astronomy at the University of California, Los Angeles. . . The comet is less than 3 billion kilometers from the sun and within a few million years, it is expected to return to its breeding grounds in the Oort cloud. The comet was first seen in 2010, but only now has the Hubble telescope confirmed its huge size. always Scientists suspected the comet’s magnitude Because it was very bright from a distance, and they were now able to confirm it. The comet is now less than two billion miles from the sun, approaching almost perpendicular to the plane of our solar system, and the closest it will reach will be within a billion miles from the sun, and it won’t be until 2031, after which it will return to the Oort cloud. Cloud), a huge reservoir of distant comets that surround the Solar System, stretching billions of miles into space.

Comets are solid bodies made of ice and rock, often called “cosmic snowballs”. They were found from the remnants of the planet formation period, 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, andWhen you get close to most of it, it gets heated up And two tails begin to extend behind them. The first consists of gas and dust, and the second is composed of electrically charged gas molecules or ions, which is the ion tail.
