Nationalgeographic.co.id-Scientist space China plans to fire 23 rocket ke outer space. Launch tens rocket This is done to divert the impact asteroid which has little chance of ending life on Earth one day.
Their target is asteroid named Bennu. This asteroid is a rock outer space weighing 85.5 million tons or 77.5 million metric tons which is within a distance of 4.6 million miles or 7.5 million kilometers from Earth’s orbit. Asteroid It is on a path that could snatch Earth’s orbit between the years 2175 and 2199.
Although Bennu’s chances or chances of attacking Earth are slim, which is only 1 in 2,700, asteroid It is quite large, which is as wide as the Empire State Building. That means, if asteroid If it hits Earth, it will be catastrophic.
The estimated kinetic energy of Bennu’s collision with Earth is 1,200 megatons, which is approximately 80,000 times greater than the energy of the bomb dropped on Hiroshima. In comparison, stone outer space that wiped out the dinosaurs produced about 100 million megatons of energy, as quoted from Live Science.
