10 times a meteor fell to Earth and flew back into space



A meteor is the fireball that occurs when a space rock (called a meteoroid) burns during its entry into the Earth's atmosphere. [1] For that reason, any space rock falling naturally on Earth will inevitably become a meteor of greater or lesser intensity. This concept serves as a starting point for the following list.

However, sometimes an alien stone falls to earth, becomes a meteor, and then for some reason decides to leave our atmosphere to continue its journey through space. Below are ten examples of meteors that showed this behavior, some of which even became impressive eyewear.

10 Japan Earth-Grazer
2006

As mentioned in the introduction, meteors commonly occur when space rocks burn and disintegrate upon entry into the Earth's atmosphere. On some occasions, such meteoroids fall in a trajectory almost parallel to their surface on the earth and "jump" in the upper atmosphere. After they have become bright meteors for a moment, these stones just go on and return to outer space. We call these meteorites "earth grinders".

On March 29, 2006, an earth grinder event occurred in Japan. A bright fireball crossed the sky over several Japanese cities, allowing multiple stations to accurately measure their trajectory and characteristics. The cause of the fireball was a meteoroid of about 100 kilograms, which arrived at an altitude of 87 kilometers in the atmosphere. From there, the meteor traveled about 1,000 kilometers (621 miles) across Japan and lasted 35 seconds before leaving Earth. [2]

This was the third near-Earth meteor that was scientifically observed and accurately measured. To determine the properties, photographs, photographs of television cameras, telescope observations and special software were used. Despite all this equipment, there are very few documented cases of earth grinders worldwide, though most items in this list fit into the category.

9 Fast Moving Fireball
1990 [19659009] On October 13, 1990, two astronomical stations discovered the passage of a near-earth meteor over Czechoslovakia and Poland. Three other independent observers in Czechoslovakia and a fourth person in Denmark also confirmed the observation. The fireball was caused by a 44-kilogram meteoroid, which descended into the earth's atmosphere to a minimum height of 98 kilometers. It moved at a speed of about 42 kilometers per second (26 miles per second), about 20 times faster than the fastest manned aircraft in the world.

The nearly ten seconds were visible in the night sky, the earth -grazer covered a distance of 409 kilometers. [3] Afterwards, the meteor left the atmosphere and returned to space at reduced speed. His mass was also reduced; After being slightly burned in the atmosphere, she lost 350 grams of material. To check the trajectory of the object, NASA performed computer simulations, the results of which were similar to direct observations and confirmed that the meteor had left Earth. A Czech camera station, which is part of the program "European Fireball Network", photographed the Earth-grazer during the flight. The picture shows the bright object moving over the visible sky near the highest point.

8 The Great Meteor
1860

On some occasions, an Earth Meteorite may fall into the atmosphere at the end, breaking into pieces. When this happens, the Earth Claw becomes a series of smaller fireballs that fly horizontally in the same direction across the sky. Some fragments disintegrate in the atmosphere while others return to space. As the lights appear to be organized and moving at a slower speed, this phenomenon is referred to as a "meteor procession". This grinder is even more unknown with just four known cases.

One of these cases occurred on July 20, 1860. It was 9:49 pm when the American painter Frederic Church and his wife (who were on their honeymoon in Catskill, New York) saw a series of bright orange meteorites covering the whole Sky crossed. Not far away, the famous writer Walt Whitman saw the same lights. In his poem, "Year of Meteors (1859-1860)," he described it as "the weird giant meteor procession shooting blindingly and clearly over our heads." Hundreds of people in the United States witnessed the fireballs and numerous newspapers The Times described also the event.

What all these people saw was a rare meteorite procession involving several meteorites crossing the North American sky from west to east. [4] The fragmented Earth Claw descended between the United States onto the Great Lakes and Canada reached its minimum height above the Hudson River in New York and moved further toward the Atlantic Ocean. After a journey of more than 1,600 kilometers, the meteorites escaped the atmosphere and left the earth behind.

7 Comet fragment
2012


20,000 years ago a large comet crashed in our solar system and gave birth to Comet Encke (officially called 2P / Encke), famed for his frequent approach to Earth. On June 10, 2012, a meteoroid of this comet visited our planet and continued its journey through space. The rock weighed 16 kilograms and entered our atmosphere about 100 kilometers above the east of Spain.

The Earth Claw moved at an amazing speed of 105,000 kilometers per hour as it moved towards the southwest of the Iberian Peninsula. After the meteor had sunk to about 98 kilometers above sea level, he regained altitude. Although the fireball was still over Spain and 32 kilometers from the Atlantic Ocean, he said goodbye to us and went back into space with minimal change in speed. However, our planet has left its mark. The burned meteoroid lost 260 grams in the atmosphere and returned to its orbit with a fusion crust, the outer layer of molten rock typical of meteorites. In total, the fireball was 510 kilometers wide (317 miles) atmosphere for 17 seconds. This former meteor has some peculiarities that distinguish it from the rest. First, it is the weakest, scientifically observed meteor of the earth whose brightness is similar to that of Venus. Moreover, it is the first such event that comes from a meteor shower. It came especially from the Zeta Perseid meteor shower, which occurs in June each year, which in turn comes from the same space debris field as the Comet Encke. [5]

6 Christmas Eve Meteor
2014


On the night of December 24, 2014, when everyone was busy on Christmas Eve, a meteor decided to go to Earth come to watch us. Then it went for some reason. A total of 13 observation stations in Spain and Portugal found that a fireball grazing on Earth was moving slowly from southeast to northwest across Europe for a meteor. The object was a stone of 100 kilograms in diameter and 1 meter in diameter, which flew at a speed of 68,400 km / h.

The meteor entered the atmosphere over North Africa glowing 105 kilometers high. Then the Earth Gripper moved on and descended to a height of 75 kilometers over Spain. There, the fireball moved so slowly that some riders had time to park to get out. The meteor continued his journey via Portugal when he ascended again. Finally, the Earth-grazer reached the Atlantic, and about 100 kilometers from the coast of Galicia (Spain), he returned to space.

The meteoroid, whose codename is SPMN241214, is a rock that is all that came from the asteroid belt between Mars and Jupiter. After his close encounter with Earth, the trajectory of the rock has been modified, though it still revolves around the sun as before. Images from the University of Huelva show that the object was very bright and left a short and narrow trail. Another shot from the Spanish province of Guadalajara (shown above) confirms the slowness of the meteor. Although the light in this video lasts about half a minute before it leaves the camera's field of view, the total duration of the fireball was one minute. [6]

5 Zagami Meteorite
1996

Not all falling stars return to space. Some rocks that were once meteors have flown back into space thanks to human intervention. In October 1962, a farmer was working in his field in Zagami, Nigeria, when he suddenly heard a loud explosion. When he looked into the sky, he saw a meteor fall down and fall to the ground only 3 meters away. The farmer noticed that there was now a 0.6 meter deep crater with a black stone in it. This stone was nothing less than an 18-kilogram meteorite from Mars. The rock was ejected from the surface of Mars after a comet impact 2.5 million years ago.

In November 1996, after two decades, NASA began its first successful mission on the Red Planet – the Mars Global Surveyor of 19459020. This mission consisted of launching a spacecraft that orbited Mars and its surface for several Should take years. However, it turns out that the spacecraft did not fly alone: ​​inside was a small piece of the Zagami meteorite, which was covered by a resin bubble. In September 1997, NASA's spacecraft began around Mars, bringing the Zagami meteorite back to where it belongs. That's right, the rock left Mars millions of years ago, turned up almost 60 years ago like a shooting star and eventually returned to its home planet. Although Mars Global Surveyor is currently inactive, it still orbits its neighbor planet and is expected to collide with the Martian surface in the future. [7] The Zagami meteorite becomes a meteor for the second time. now in his own world.

4 Unconfirmed Earth Grazer
1996/2012


Meteors are so short and unpredictable that it is difficult to determine where the next one will occur. It is even more difficult to know if certain sightings were actually meteorites that have fallen into space. On October 3, 1996, an unusual shooting star crossed the night sky of New Mexico and then disappeared. But 100 minutes later, the same fireball flew over California and exploded. It is believed that the meteor was a rock that rebounded in the atmosphere and nearly completed a full orbit before falling back over Southern California. The reports, however, remain unconfirmed.

Meanwhile, at 11:00 pm on September 21, 2012, thousands of people in England, Scotland, and Ireland witnessed a fireball (shown above) flying through the sky. The light moved slowly and lasted about 40 seconds before disappearing. Two and a half hours later, another shooting star with the same characteristics crossed the sky over Canada and the United States. [8] In some countries, the emergency numbers were crowded with hundreds of calls from people who feared fireball.

Soon the mathematician Esko Lyytinen, a member of the Astronomical Association Ursa (Finland), stepped in and explained that the meteorites of 21 September were related. Both were the result of a single space rock that burned in the sky over Ireland at a height of 53 kilometers, but had enough speed to fly back into space. However, this entry into the atmosphere caused the rock to lose speed. After 155 minutes and a full orbit around the earth, the remnants of the meteoroid reentered the atmosphere over North America and ended its crazy flight there. With limited information on the speed and angle of the meteors, some experts have questioned this claim, but the possibility of a new ground grinder still exists.

3 Rare Aten Asteroid
2007


Information on The following Erdgrazer meteor, called EN070807, is scarce. All available references come from a single publicly available article on the Ondrejov Observatory, which belongs to the European Fireball Network in the Czech Republic. Because the European Fireball Network names meteorological events with an abbreviation of the date on which they occurred, the codename of this grinder indicates that it visited Earth on August 7, 2007.

EN070807 is actually an Atenoid atenoid. Atenoids are rocky fragments that orbit the Sun at frequent intervals, and it is believed that most of them are from the asteroid belt. Many Aten asteroids occasionally cross Earth's orbit, potentially posing a threat to our planet. In the case of EN070807, the encounter with Earth may have had its original orbit of the Aten type but its trajectory could have changed.

While the EN070807 descended above the European sky, several stations in the Czech Republic photographed the event. This allowed the European Fireball Network to include the Earth-grazer in the above six-monthly report along with 44 other conventional fireballs. [9] Like the other meteors on this list, EN070807 lost material during its brief passage through the Earth's atmosphere. The rest of his body still swims there.

2 Campo Del Cielo meteorite
2014

The Zagami meteorite is not the only extraterrestrial rock that humans have sent back into space. For 4.5 billion years, a large iron body roamed the universe until it collided with the earth 4000 years ago. The meteorite fell in Argentina, and the locals call the impact zone "Campo del Cielo" (Field of Heaven).

In 2012, Scottish artist Katie Paterson acquired a small Campo del Cielo meteorite that melted at 1,700 degrees Celsius (3,092 ° F) and restored it to its original shape. The old new meteorite weighing 680 grams was then transferred to a European Space Agency facility in the Netherlands. And in July 2014, it was launched aboard the spacecraft aboard the spacecraft [GeorgesLemaitre .

The meteorite was unpacked and prepared for return to Earth in the same spacecraft that took him there. Finally, in February 2015, the meteorite had a destructive re-entry into the Earth's atmosphere. [10] It differs in at least two points from the Zagami meteorite. At first, the meteorite Campo del Cielo was twice a meteor. And second, it was twice a meteor in our own atmosphere. Therefore, Paterson's work has been internationally recognized, and it has been proven that a meteor that falls to the ground does not have to do it once.

1 The Great Daylight Fireball
1972

While all the other Earthquake Meteors we have seen on this list occurred at night or under poorly-studied conditions, the following event occurred in the broad daylight in front of thousands of people. For this reason, it is the most well-known grabber, and it is widely known as the Great Daylight Fireball. It was 2.30 pm on August 10, 1972, when a space rock over the state of Utah reached the atmosphere. And for a minute and a half, it crossed the sky in a northerly direction. The meteor left the earth via Alberta (Canada).

The Earth Gripper generated enough heat during its passage through the atmosphere to be detected by a US Air Force satellite that received data on its velocity and trajectory. After several investigations, it was found that the object reached our planet at a speed of about 54,100 kilometers per hour. The meteoroid would have a maximum mass of 570 tons and a length of 14 meters (46 feet) – about the size of a truck (but much heavier). When the object escaped from the atmosphere at a height of about 102 kilometers, its size became at most 10 meters.

Its closest approach to the earth's surface was 58 kilometers above Montana. Due to the low altitude, people near the site could hear acoustic booms from the meteor in the sky. There are several fireball recordings, such as a 20-second video showing his path, or a photograph of Earth-grazer flying over the Teton Mountains, Wyoming. Well, we all know the result of this story, but it is believed that the object would have had the destructive power of an atomic bomb if the object hit Earth. [11] We can thank the Meteor for being in a good mood this day.
