Man saw it with his own eyes! 1994 There was a celestial collision, which was equivalent to 4 trillion tons of TNT explosion.

1994, mankind witnessed a big collision. Fortunately, the object of this collision is not the earth, but Jupiter, the largest planet in the solar system. This big collision event is called "coma collision"

What hit Jupiter was a comet-Shoemaker-Levi 9 (hereinafter referred to as SL9). The impact event lasted for more than five days, and fragments of SL9 kept hitting Jupiter. How much energy did it cause? It is equivalent to detonating 2 billion atomic bombs without interruption, and TNT high explosive releases about 4 trillion tons of energy when it explodes. The explosion energy equivalent to Hiroshima photoelastic is 65.438+0 billion times. This is the first time in human history to witness the collision of celestial bodies. Although the comet did not break Jupiter, Jupiter also suffered heavy losses. Leaving four deep pits with a diameter of tens of thousands of kilometers.

And the diameter of these deep pits is several times that of the earth. And such a big collision will always happen in the universe, but we have observed very little. Take the solar system as an example. Except Jupiter, any other planet is in danger of being hit, but all other planets are fine. If a massive asteroid hits the earth, the destruction of the earth will not be a joke. As we know, the impact event on the earth is the extinction of dinosaurs, and the consequences of the impact are serious. The era when dinosaurs ruled the earth ended completely, and the earth entered a moment of silence, and then after rebirth, intelligent life gradually appeared. Imagine if there was life on Jupiter, how much harm the comet that hit Jupiter would bring to life on Jupiter. Fortunately, there is no life on Jupiter, and the impact event did not have much impact on the earth.

However, it is worth noting that asteroid impact is an absolute threat to the earth. In recent years, asteroids have appeared near the earth. Although it didn't bring any big sparks, it also indicates that our planet is facing many threats, and there may be another collision event. At present, the asteroid that poses the greatest threat to the earth is Apophis, which is big enough to destroy the earth. At present, scientists are also closely observing the trajectory of this asteroid.
