The astronomical phenomenon could be seen in at least three Japanese provinces last Friday. NASA compared the fact with a “small nuclear explosion.”
A “Brilliant Ball” He illuminated Japan’s night sky, in a phenomenon that surprised everyone with the transformation of darkness in clarity for a few seconds. The incident occurred last Tuesday, August 19, at 23:08 premises.
The phenomenon could be observed from different regions of the country. Inhabitants of Kyushu, Shikoku and Kagoshima They published videos on social networks that quickly became viral.
The NASA version
According to the POT and the center of objects close to Earth (CNEOS), crossing the atmosphere, the racing released an estimated energy of 1.6 kilotons, magnitude that is equivalent to “a small nuclear explosion.” Then, he disintegrated on the Pacific Ocean, southeast of Kyushu.
According to a preliminary report of the Sonotaco network, The rock entered with a speed of about 21 km per secondan angle of 58 ° and reached a final altitude close to 18 km.
What are the cars
NASA describes in its official portal the fireballs as “Exceptionally bright, so spectacular meteors that can be seen in a very extensive area. ”
In relation to the glow of the cars, the agency explained: “During the atmospheric input phase, an object that impacts is slowed and heated by atmospheric friction and in front of it, a shock wave is generated where atmospheric gases are compressed and warmed up.”
“Part of this energy radiates to the object, causing its ablation and, in most cases, its fragmentation. Fragmentation increases the amount of intercepted atmospherewhich enhances ablation and atmospheric braking. The object disintegrates catastrophically when the force of unequal pressures on frontal and posterior faces exceeds their tensile strength, ”they concluded.
