Comet Leonard: Green Comet Leonard is about to pass close to Earth, this is the first time in 70000 years


The recently discovered Leonard Comet is near to pass near Earth in December. This can be the primary time in 70,000 years that a comet with a green tail will come so near Earth. Within the hemisphere, it can be seen within the east with the assistance of a telescope. During this, the glow of Leonard Comet are going to be on its face.


Astronomers say it's going to be possible to see this bright green Comet after sunset in Southern Side of Earth later this month. People in Northern Side of Earth will be able to see this comet in East Direction Sometime before Sunrise or Dawn. During this point a green tail of this comet will be visible. Scientists told that the closer the inside part of this Comet gets to Sun, the warmer it gets. First it emits blue dust, then yellow or white and eventually green. 


The green tail means this comet is extremely hot. it's plenty of cyanide and diatomic carbon and is equally likely to interrupt down. Unfortunately, it'll be very difficult for skywatchers within the UK to determine Leonard. Within the remainder of the planet, this comet will be seen with bright light within the sky for several days after December 10.


We've may have an opportunity to see this Comet over the southwest horizon after sunset on Christmas. It depends on where within the world you're. This Comet is Predicted to be at its brightest stage in Late December. Leonard Comet was discovered by astronomer Gregory J. Leonard on January 3 from the Mount Lemmon Infrared Observatory in Arizona. it had been earlier listed as C/2021 AI.


It will be closest to Earth and brightest on December 12. During this point its distance from Earth will be about 21 million miles (35 million km). When it had been first seen, it had only atiny low amount of shine. in line with scientists, at that point its light was 160,000 times dimmer than rock bottom light stars visible to the traditional eye.

The giant comet coming towards the earth, the largest ever, makes one revolution in 6 lakh years

The giant comet coming towards the earth, the largest ever, makes one revolution in 6 lakh years


A 'supercomet' coming from the outer a part of our Solar system was believed to be a dwarf planet for its size. it'll not go very near the Sun and can pass near Saturn. Scientists are very excited to review it because its size is big and also the distance is additionally short which is rare. This comet was coming from a part of the named Oort Cloud, which is extremely important to review in itself and may also reveal many mysteries of the system.

This comet has not come to our Solar System for 3 million years. We do not know much about the outer part of the Solar System yet. Therefore, scientists are more inquisitive about the objects coming from there. The comet was discovered by University of Pennsylvania astronomer Gary Bernstein and his team. He has given more information about this within the new paper. The paper states that C/2014 UN271 (Bernardinelli-Bernstein) has not previously come closer than 18 astronomical units to the Sun.


The team has found in its analysis that it started its journey towards the sun at a distance of 40,400 AU. It comes in Oort cloud. This part goes between two thousand and one thousand thousand AU and is home to icy objects. When it was discovered it was at a distance of 29AU. it's believed that it'll be closest to the Sun in 2031 after 10 years at 10.97AU.

Its size is 155 km diameter but thanks to the gap it'll be visible only with the assistance of telescopes. Studying it's special because it's believed that these icy rocks haven't changed much since the formation of the Solar System 4.5 billion years ago. On the idea of its chemical composition, we'll also get to understand about the Early Solar System. It takes 6.12 lakh years, not some days, to finish one revolution in its orbit. within the last seven years it's been covering a distance of 1 AU each year.

Comets also revolve round the sun like asteroids but they're not rocky but made from dust and ice. When these comets move towards the sun, their ice and dirt develop into vapor, which appears like a tail to us. The special thing is that the comet visible from the Earth is truly very distant from us. At the identical time, the Oort Cloud is a vicinity where there's gas and dirt that revolves around the Solar System.
Sky 'guests' returned from history? Comet ATLAS was shown 5000 earlier, claims in new study

Sky 'guests' returned from history? Comet ATLAS was shown 5000 earlier, claims in new study


A comet is believed to possess reached 23 million miles near the sun about 5000 years ago. The period was happening on Earth then and it should are seen from Eurasia to geographic region. However, it's not mentioned anywhere. Actually, astronomers saw comet ATLAS (C/2019 Y4) within the year 2020 and it's believed that it absolutely was a part of the identical ancient comet.

Comet ATLAS was first discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS), which is operated by the University of Hawaii. It resulted to split into small icy pieces in mid-2020.

In a new study, with the assistance of the American Space Agency NASA's Hubble Space Telescope, Astronomer Quanzhi Ye has told that ATLAS is an element of the identical 5000-year-old comet. in line with astronomers from the University of Maryland in College Park, ATLAS is on the identical track that a comet was observed in 1844. That is, both may have come from the identical parent comet. The link between the 2 was discovered by an astronomer named Mike Meyer.


It says that ATLAS must have broken when it had been 100 million miles far from the Sun than Earth. The question is that if it had broken far-off from its parent, then how did it pass near the sun? In a study published within the Astronomical Journal, Yee, together with his colleagues, reported that one a part of the ATLAS broke within some days and the other several weeks later.

One possibility is that the materials emanating from it made it spin so fast that it broke thanks to its force. Another theory is that the ice in it had become so explosive that the comet exploded like fireworks. It says that ATLAS is extremely difficult to know but the remainder of it'll not return before the 50th century.
