![]() ![]() When Bennu spins, the side of its body facing the sun absorbs heat and spins away. Although this half-kilometer-wide asteroid is only one twentieth the size of the asteroid that killed the dinosaurs, a direct impact on the continent is still devastating.Īlthough researchers have a good understanding of the path of this asteroid, it may be affected by the Yarkovsky effect. Part of the reason is that the orbit of the asteroid named Bennu around the sun is similar to that of the Earth, so the two celestial bodies occasionally get close to each other, which makes it easier for the spacecraft to reach the asteroid and return again. Why is NASA this asteroid named Bennu the target of research? The data already collected by the mission is used to recalculate Bennu's path, thereby recalculating its chance of hitting the earth. The spacecraft is returning to Earth and is expected to arrive on September 24, 2023. ![]() The team must simulate the gravitational interaction between the asteroid and the sun, other planets and their moons, and more than 300 other space rocks, as well as the pressure from the solar wind. When trying to map its path through the solar system, several factors need to be considered. OSIRIS-REx provides scientists with the most accurate data on Bennu's size, shape, mass, spin, chemical composition, and orbital motion to date. The research data released by NASA is not groundless, but a large amount of data obtained through the spacecraft OSIRIS-REx orbiting the asteroid for 2 years. Many countries in the world also have evidence of the impact of the Earth: the Botais crater in Ukraine, with a diameter of 24 kilometers the Silver Crater crater in the North Sea of the United Kingdom, with a diameter of 20 kilometers and the Shiva crater off India. The alien impact on the Earth is not a hypothetical rumors made out of thin air, but a real recorded phenomenon in 1994, Comet Shoemaker-Levy 9 split due to tidal forces, and several fragments were in the next Hit Jupiter one after another within a few days. The impact caused a global fire, and a large amount of soot entered the air, which eventually led to the extinction of the dinosaurs. The extinction of the dinosaurs 65 million years ago occurred when, according to relevant scholars, a huge asteroid hit the earth and caused a major earthquake. #Scientists finetune asteroid bennu movieWhether it is from historical records or movie footage, we know that the impact of an alien planet's impact on the earth is devastating. Speaking of comets hitting the earth, perhaps everyone is familiar with it. ![]()
