Earlier this month, a huge fireball exploded in Earth’s atmosphere. Witnesses said they heard “deep explosive sounds” and “long rumbles like thunder or an engine” as the meteor hit the atmosphere.
CCTV video showed the meteor exploding into the night sky, producing a bright explosion as it did so.
When meteors produce such an intense burst of light, they are called fireballs in astronomical terms.
This fireball hit Earth on November 7, and astronomers said it was traveling at a staggering 61,000 kilometers per hour when it hit Earth.
At that speed, it could easily circle the Earth twice in under an hour.
The analysis of the Norsk Meteornettverk said it “entered the earth’s atmosphere at a speed of 17.4 km / s and an inclination of 70.4 degrees”.
According to the analysis, the meteor entered the atmosphere 100 kilometers west of Stockholm, Sweden.
However, the fireball was so bright that it could also be seen in Denmark and Norway.
The International Meteor Organization (IMO) stated: “On 7 November 2020, around 21h 27min UT, a very bright fireball was observed and captured by the camera over Scandinavia.

The IMO said: “Fireballs are meteors that appear brighter than normal.
“Because of the speed with which they hit Earth’s atmosphere, fragments larger than a millimeter have the ability to produce a bright flash as they cross the skies above.
“These bright meteors are what we call fireballs and often arouse fear and amazement for those who witness them.”
Perhaps the most famous fireball in modern history came when a meteor hit Chelyabinsk in 2013.
The explosion, caused by a 20-meter meteor, was so powerful that it broke windows across the city and injured more than 1,000 people.
