Every fireball meteor that has hit Earth’s atmosphere in the past 33 years revealed in a new map

A new map shows where hundreds of fireball meteors, an unusually bright meteor that can shine brighter than Venus, have struck Earth’s atmosphere over the past 33 years.

The Center for Near Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory compiled data from 1988 to 2021 on fireballs detected by government sensors.

The world map shows points, of four different sizes and colors, which are proportional to the impact energy (kinetics) of each fireball, the total energy that the meteoroid brought into the atmosphere due to its speed.

Scientists use the kinetic energy given off by the fireball, sound waves, and energy at other wavelengths to determine size before it even enters Earth’s atmosphere.

Using such calculations helped scientists determine the fireball meteor that fell on Chelyabinsk, Russia on February 15, 2013 was 65 feet in diameter, which is the largest shown on the map.

This fireball exploded over the Ural Mountains, causing a shock wave that shattered windows, damaged buildings and injured 1,600 people.

The meteorite shattered into several pieces when it entered the atmosphere, scattering debris and creating a shock wave estimated at 20 atomic bombs from Hiroshima.

The second largest cluster of fireballs shown on the map mainly fell around the Pacific Ocean and neighboring countries, such as Fiji and other islands surrounding Asia.

The United States has been hit by smaller meteorites, but not as many as other parts of the world.

Paul Chodas, director of CNEOS, said in a statement: “More people see meteors during a shower because there are so many of them. For the Perseids, there are up to 100 meteors per hour.” fire, on the other hand, are quite rare and can occur any day of the year “

METEORS BALL OF FIRE: FRAGMENTS OF AN ASTEROID

Sometimes referred to as a shooting star, a fireball is a rapidly moving space rock within Earth’s atmosphere.

According to NASA, if a meteor is able to survive this scorching journey and hit the ground, the rock on Earth becomes known as a meteorite.

Pieces of rock often come from asteroids that have broken apart as a result of a collision or other event.

Some were pieces of other planets or even the Moon.

A piece of Martian rock that fell to Earth as a meteorite is on the Perseverance rover to help calibrate its equipment.

By studying different types of meteorites, scientists can learn more about asteroids, planets, and other parts of our solar system.

However, most of those rare meteors that have entered Earth’s atmosphere since 1988 appear to have shattered over one of the planet’s five oceans and have likely gone unnoticed by most humans.

Paul Chodas, director of CNEOS, said in a statement: “More people see meteors during a shower because there are so many of them. For the Perseids, there are up to 100 meteors per hour.

“Fireballs, on the other hand, are quite rare and can occur any day of the year.”

The spectacular Perseid meteor shower, which occurred earlier this month, saw between 40 and 100 fireballs cross the night sky every hour from August 11 to 13.

NASA photographer Bill Ingalls captured a stunning photograph of a meteor passing overhead on August 11 from the summit of Spruce Mountain in West Virginia.

A few thin clouds lingered, reflecting light from remote urban areas.

The meteor in the photo appears to look green in some areas, which Bill Cooke, head of NASA’s office of the meteorological environment, said was due to how the meteoroid excited oxygen molecules during of its impact with the atmosphere.

Cooke also noted that the Perseid rain is particularly rich in bright meteors.

He pointed to data from NASA’s All-Sky Meteor Camera Network, which can detect meteors brighter than Jupiter.

“The number of bright meteors in the Perseids eclipses all other meteor showers, 30% more than the Geminid rain, which has better rates and is also known for bright meteors,” Cooke said in a statement.

Explained: The difference between an asteroid, a meteorite and other space rocks

a asteroid is a large chunk of rock left over from collisions or the start of the solar system. Most are located between Mars and Jupiter in the main belt.

A comet is a rock covered with ice, methane and other compounds. Their orbits move them much further away from the solar system.

A meteor is what astronomers call a flash of light in the atmosphere when debris burns.

This debris itself is known as a meteoroid. Most are so small that they vaporize in the atmosphere.

If any of these meteorites land on Earth, it is called a meteorite.

Meteors, meteorites, and meteorites normally originate from asteroids and comets.

For example, if Earth passes through the tail of a comet, much of the debris burns in the atmosphere, forming a meteor shower.
