NASA NASA has downgraded the risk of asteroid 2024 YR4 hitting Earth in 2032 to 1.5 per cent, or1-in-67, down from a high of a1-in-32chance, which was the highest odds yet of collision. Astronomers discovered that the asteroid wasbarrelling towards Earth in Decemberand it ...

intersects the path of the planet. That would make the odds of a collision still quite small, about 1 in 32.The European Space Agency'speak probability estimatewas slightly lower, at 2.8%. Last week, NASA and the ESA agreed the probability of an asteroid strike was closer to 2%."However...
1What do scientists say about the collision of an asteroid with Earth? A. It is very unlikely but the danger exists. B. Such a collision might occur once every 25 years. C. Collisions of smaller asteroids with Earth occur more often than expected. D. w.c2cedu.com/zhuanti/kaobo/yingyu...
And that is already feeding into discussions about how to possibly one day divert a threatening asteroid from a collision with Earth. "The OSIRIS-REx mission has collected a phenomenal data set about asteroid Bennu, which is a potentially hazardousasteroidwith approximately (a) 1-in-2,700 chance...
“Level 8 means a certain collision,” Binzel says. 尽管看似遥远,但2024 YR4的撞击风险仍然值得关注,麻省理工学院的行星科学家理查德·宾泽尔表示,他于1997年创建了托里诺等级。1%的概率似乎微不足道,2032年底看起来也很遥远,但这个几率可能会迅速恶化,而尝试偏转或减轻撞击物的措施则需要多年时间来规划和执行...
We probably don't have to worry about a potential civilization-ending strike anytime soon. NASA researchers have mapped out the orbits of 90 percent of the biggest and most dangerous near-Earth asteroids, and none of them seem to be on a collision course with Earth in the foreseeable future...
In an event stirring both excitement and a heightened sense of cosmic awareness among astronomers and the public alike, a stadium-sized asteroid, known as 2008 OS7, will make a close approach to Earth today, February 2, 2024. This asteroid, recognized for its significant size and its c...
