An asteroid NASA's been tracking for nearly 25 years could impact Earth in the future, a new report reveals. First discovered in 1999, Bennu, the near-Earth asteroid, could possibly drift into the planet's orbit

Near Earth Asteroid Animation What if an asteroid were going to hit Earth? There are no known threats to Earth, but planetary defense expert Dr. Kelly Fast says it’s important to find the asteroids before they find us. That’s why NASA’s Planetary Defense Coordination Office keeps it...
"Surely this possibility will soon be ruled out," he tweeted last week. "However, as an exercise, I calculated where the asteroid might fall if this possibility occurred." A map of his calculations – which could change over time – show that if it were to collide with Earth, it ...

DART任务始于2021年11月,当时美国宇航局用猎鹰9号火箭向太空发射了一艘宇宙飞船,任务是撞击距离地球1100万公里的小行星迪莫弗斯。这项测试旨在帮助人类保护自己免受未来可能发生的碰撞。撞击计划在今晚进行。 Dimorphos是一个小型的“卫星”,它围绕一颗更大的小行星Didymos运行,Didymos距离地球1100万公里。虽然这不是对地...
