The comet will fly to the earth. Two comets will fly over the earth at once this fall and winter

Comets are one of the most mysterious celestial bodies that appear in the sky every now and then. Today, scientists believe that comets are a byproduct left over from the formation of stars and planets billions of years ago. They consist of a core of various types ice (frozen water, carbon dioxide, ammonia and methane mixed with dust) and a large cloud of gas and dust surrounding the core, often called a "coma". Today, more than 5260 are known. Our review contains the brightest and most impressive.

1. Great Comet of 1680

Discovered by German astronomer Gottfried Kirch on November 14, 1680, this magnificent comet became one of the brightest comets of the seventeenth century. She was remembered for being visible even in the daytime, as well as for her spectacular long tail.

2. Mrkos (1957)

Comet Mrkos was photographed by Alan McClure on August 13, 1957. The photo made a great impression on astronomers, since for the first time a double tail was noticed on a comet: a straight ion tail and a curved dust tail (both tails are directed in the opposite direction from the Sun).

3. De Kock-Paraskevopoulos (1941)

This strange but beautiful comet is best remembered for its long but faint tail, and for being visible at dawn and dusk. The comet received such a strange name because it was simultaneously discovered by an amateur astronomer named De Kock and the Greek astronomer John S. Paraskevopoulos.

4. Skjellerup - Maristani (1927)

Comet Skjellerup-Maristany was a long-period comet whose brightness suddenly increased greatly in 1927. It was visible to the naked eye for approximately thirty-two days.

5. Mellish (1917)

Mellish is a periodic comet that has been observed primarily in the southern hemisphere. Many astronomers believe that Mellish will return to earth's horizon in 2061.

6. Brooks (1911)

This bright comet was discovered in July 1911 by astronomer William Robert Brooks. It was remembered for its unusual blue color, which was the result of radiation from carbon monoxide ions.

7. Daniel (1907)

Comet Daniel was one of the most famous and widely observed comets of the early twentieth century.

8. Lovejoy (2011)

Comet Lovejoy is a periodic comet that comes extremely close to the sun at perihelion. It was discovered in November 2011 by Australian amateur astronomer Terry Lovejoy.

9. Bennett (1970)

The next comet was discovered by John Caister Bennett on December 28, 1969, when it was two astronomical units from the Sun. It was notable for its radiant tail, composed of plasma compressed into filaments by magnetic and electric fields.

10. Seki Lines (1962)

Initially visible only in the southern hemisphere, Seki Lines became one of the brightest objects in the night sky on April 1, 1962.

11. Arend-Roland (1956)

Visible only in the southern hemisphere during the first half of April 1956, Comet Arend-Roland was first discovered on November 8, 1956 by Belgian astronomers Sylvain Arend and Georges Roland in photographic images.

12. Eclipse (1948)

Eclipse is an exceptionally bright comet that was discovered during a solar eclipse on November 1, 1948.

13. Viscara (1901)

The great comet of 1901, sometimes called Comet Vizcar, became visible to the naked eye on April 12. It was visible as a second magnitude star with a short tail.

14. McNaught (2007)

Comet McNaught, also known as the Great Comet of 2007, is a periodic celestial body discovered on August 7, 2006 by British-Australian astronomer Robert McNaught. It was the brightest comet in forty years and was clearly visible to the naked eye in the southern hemisphere in January and February 2007.

15. Hyakutake (1996)

Comet Hyakutake was discovered on January 31, 1996, during its closest passage to Earth. It was named the "Great Comet of 1996" and is remembered for being the closest celestial body to Earth in the last two hundred years.

16. Vesta (1976)

Comet Vesta was perhaps the most exciting and eye-catching comet of the last century. It was visible to the naked eye, and its two huge tails stretched across the entire sky.

17. Ikeya-Seki (1965)

Also known as the "Great Comet of the Twentieth Century", Ikeya-Seki was the brightest comet of the last century, appearing even brighter than the Sun in daylight. According to Japanese observers, it was about ten times brighter than the full moon.

18. Halley's Comet (1910)

Despite the appearance of much brighter long-period comets, Halley is the brightest short-period (it returns to the Sun every 76 years) comet that is clearly visible to the naked eye.

19. Great Southern Comet (1947)

In December 1947, a huge comet was spotted near the setting sun, the brightest in decades (since Halley's Comet in 1910).

20. Great January comet (1910)

This comet was visible during January 17, 1910, as a snow-white object with a long and wide tail.

21. Great comet of 1577

Comet Hale-Bopp was perhaps the most widely observed comet of the twentieth century, as well as one of the brightest in modern history. It was visible to the naked eye for a record year and a half, twice as long as the previous record holder, the Great Comet of 1811.

24. Great September comet (1882)

It was a comet that became so bright in September 1882 that it could be seen close to the sun at perihelion.

25. Kohoutek (1973)

And the last comet on the list was first discovered on March 7, 1973 by Czech astronomer Lubos Kohoutek. It reached its perihelion on December 28, 1973, and its previous appearance is believed by astronomers to have been about 150,000 years ago. Comet Kohoutek will next return in about 75,000 years.

Especially for those interested in astronomy and science.

Scientists argue that it is not even the celestial body itself that poses a special risk, but the gas and dust plume of comet Hulk, which will bring with it climate change, typhoons, tornadoes and other catastrophic consequences for human life.

All inhabitants of the Earth will know that a dangerous comet will approach the Earth on August 7, 2018, since seeing it is like the brightest star in the night sky can be seen with the naked eye. Comet Hulk is twice the size of the planet Jupiter, and its greenish-blue color will illuminate the sky with an unusual radiance. Watch for a unique phenomenon It will be possible from Tuesday, August 7 to Thursday, August 16, 2018, when the visibility of parts of the comet will be maximum.

Initially, Comet Hulk did not have a tail, and scientists watched its movement across the sky through a telescope, fearing for life on our planet. However, in mid-July 2018, the incredible happened: an unknown force literally tore the comet into several pieces!

On the one hand, this guaranteed that the end of the world would not take place in August 2018 due to a collision with a dangerous comet. But after a sharp rupture of the celestial body, a gas and dust plume was formed that will attack the Earth throughout the last month of summer.

According to experts, asteroid 2018 will bring with it new weather anomalies: tornadoes and tornadoes are expected in the United States, and prolonged cyclones will sweep across Europe, when incredible heat will abruptly give way to cold weather. High-precision equipment will begin to fail, sudden accidents are possible at power plants, and pilots of passenger aircraft will lose control of the aircraft.

News about the 2018 meteorite suggests that Comet Hulk was supposed to be a harbinger of the end of the world and become a formidable warning that the End of the world in 2018 would come due to the planet Nibiru.

The comet that broke up into pieces poses an even greater threat to humanity than before due to the fact that the substances contained inside the nucleus of the Hulk comet burst out. Russian researcher of cometary meteorites, astronomer Evgeny Dmitriev, said that the gas and dust cloud is 260 thousand kilometers in diameter. Ionized plasma can only be partially neutralized by the atmosphere of planet Earth, but even this will be enough for residents of different parts of the world to observe unusual phenomena in the atmosphere, which are often mistaken for UFOs.

On September 18, the two-kilometer comet will be at its minimum distance from our planet. Comet 21P/Giacobini-Zinner appeared in the sky, hiding beyond solar system since February 2012. That is, 6.6 years. This is the period of her conversion.

The comet was discovered on December 20, 1900. As the Latin letter “P” in its name suggests, it is periodic, and its orbital period is 6.6 years. The comet will pass perihelion, that is, the point of closest approach to the Sun, on September 12, and a few days later the distance between it and the Earth will be minimal - it is then that the brilliance of the celestial body will be the brightest. See space object residents of the Northern Hemisphere can, and every night it gets closer to the horizon.

Which comet is approaching Earth: what is known about comet 21P Giacobini

Comet 21P Giacobini/Zinner, the source of the Draconid meteor shower, is already passing over the Earth and can be observed even in small telescopes. Soon Giacobini/Zinner will approach the Earth at its closest distance to us in the last 72 years!

Another comet, Wirtanen, will come even closer. We can probably see it with the naked eye. But for now it is only approaching the Earth, and it will become available for observations at the beginning of winter.

On September 12, 2018, the comet will pass perihelion, the closest point to the Sun. It will appear from our star at approximately the same distance as the Earth. A few days later - September 18 - the distance between the comet and our planet will decrease to a minimum. But it will still remain impressive - about 55 million kilometers. A collision with the comet itself is ruled out. But with its particles - for sure.

Comet 21P/Giacobini-Zinner regularly litters—leaving a trail of its particles. Scatters ice flakes, dust particles and pebbles, which fall to the Earth as a meteor shower from the Jacobinids shower. Or Draconids, as it is also called. The second name is due to the fact that the radiant of the shower, the area that appears to be the source of meteors, is located in the constellation Draco. A collision with particles from comet 21P/Giacobini-Zinner is inevitable. The earth crosses their stream every year. The meteor shower caused by it can be observed in the first third of October. Astronomers expect peak activity on October 8-10. No one knows for sure how many “falling stars” we can count on. However, it happened that they fell in real downpours. The number of meteors exceeded a thousand per hour. Or even ten thousand. This happened in 1899, 1933 and 1946.

Astronomers estimate the diameter of the comet's nucleus to be 2 kilometers. Approaching the perihelion and passing it, the guest will “flare up.” And most likely it will become accessible to observation with the naked eye.

Which comet is approaching Earth: By mid-September 2018, the comet will be in the constellation Auriga

The comet was discovered twice. In 1900, it was discovered by the French astronomer Michel Giacobini - he saw it in the constellation Aquarius. More than 13 years later, after the comet made two revolutions in its closed orbit, it was noticed by the German astronomer Ernst Zinner. I saw it already in the constellation Scutum. I thought that I had discovered some new comet, but it turned out that it was the same one discovered by Giacobini. The comet eventually received a double name, taking into account the merits of both astronomers.

Comet Halley, captured in 1986

– comet of the Solar System: period of revolution, photo, history of research, year of Halley’s comet, eccentricity, when it arrives, semimajor axis.

Halley's Comet is a short-period comet that arrives at our planet every 75 years. The last time we saw her was in 1986. If you're wondering when it will arrive back, Earth expects it to return in 2061.

The comet was named after Edmund Halley, who investigated its arrivals in 1531, 1607 and 1682. He realized that all three comets were the only returning object. So he was able to predict that 1758 should be perceived as the year of Halley's Comet.

Halley did not live to see this moment, but his conclusions turned out to be correct. Moreover, his calculations showed that a certain category of comets constantly returns to Earth. In 1986, telescopes on Earth monitored the arrival of Halley's Comet, and some spaceships they even planned to take samples.

It is difficult to observe because the period of Halley's Comet spans decades. Therefore, scientists focus on other objects to compare and infer class characteristics. For example, the analysis of 67P/Churyumov-Gerasimenko showed that the composition of water on comets differs from that on Earth.

History of Halley's Comet

The first record of a comet was left in 239 BC. e. Listed in the Chinese chronicles of Shin Shi and Wen Xiang Tong Khao. The ancient Greeks left a record in 466 BC. e. The return was recorded in Babylon in 164 and 87. BC. These texts are important because they allow us to study its orbital path in the past.

The arrival in 1301 inspired the artist Giotto to paint The Star of Bethlehem, which tells the story of the victory of William the Conqueror. At that time, scientists thought that each event indicated the arrival of a new object. They were often seen as harbingers of disasters. This is also noticeable in Shakespeare's play Julius Caesar, where one of the lines says that comets mark the death of kings.

Detection of the periodicity of Comet Halley

Even during Shakespeare's lifetime, astronomers were inclined to believe that the Sun stood at the center of the solar system. Many years passed until a whole powerful concept was established that forces us to take a fresh look at our place in the Universe (the heliocentric system).

In 1705, Edmund Halley completed his study of 24 comets and published An Astronomical Summary of Comets, which noted the objects that arrived in 1337-1698. Three of them coincided in orbits and other parameters, and he assumed that they were all a single object. He also calculated that her arrival should be expected in 1758.

The comet arrived on time and was followed by inspired scientists from all over the world. Halley's Comet is shown in the photo below.

The comet's return in 1910 was especially impressive because it came within 22.4 million km of us. It was this year that we received her first photo. It's amazing that Mark Twain accurately predicted his death. He wrote that he arrived with the comet in 1835 and would leave with the next arrival. This happened on April 21, 1910.

Space Age

In 1986, humanity was able to use spaceships for the first time in research. And it was a good moment, because it came close to the planet. Several devices called “Halley's Armada” were sent to the comet. The Soviet-French mission Vega 1 and 2 went to the object and one even managed to image the core. Two probes also flew from Japan.

Photos of Halley's comet have also been received from NASA's International Cometary Explorer, which has been operating since 1978. The photographs were taken at a distance of 28 million km.

The arrival of the comet also marked a tragic event. The crew of the Challenger STS-51L planned to follow her. But on January 28, the ship exploded during takeoff and 7 astronauts died.

The re-arrival is still decades away, but we can keep track of cosmic remnants in space. We are talking about the Orionid meteor shower in October.

In 2061, Halley's Comet will be on the same side of the Sun as Earth and will be much brighter. Scientists believe its periodicity is still questionable because a collision with any object would push it back for thousands of years.

Its brightness is predicted to reach an apparent value of -0.3. There are also objects included in the “Halley family of comets.” They converge in orbital characteristics. But there are also inconsistencies, which means they may have a different origin. Perhaps they are members of the Oort cloud or created from the centaurs (between Jupiter and the Kuiper belt).

Scientists are not sitting idle while waiting for the comet. In 2014-2016 We had the amazing opportunity to visit comet 67P/Churyumov-Gerasimenko and analyze samples. In the same way, the researchers studied 81P/Wilda and 9P/Tempel.
