30 kwi 2021 · NASA held a tabletop exercise this week in which planetary defense officials pretend a near-Earth object is about to collide with the Earth.
When Apophis made a distant flyby of Earth around March 5, 2021, astronomers took the opportunity to use powerful radar observations to refine the estimate of its orbit around the Sun with extreme precision, enabling them to confidently rule out any impact risk in 2068 and long after.
The space tracker you can take anywhere. Track noteworthy space objects in your browser in a 3D simulation of the solar system.
In fact, collisions of asteroids with the early Earth may have been the key to delivering water to our planet (e.g., Daly & Schultz, 2018), enabling life as we know it. Now, billions of years later, the influx of small bodies in the inner Solar System is much lower.
In Id Software's video game Rage, the backstory involves the asteroid colliding with Earth on August 23, 2029. The asteroid almost wipes out the human race and ushers in a post-apocalyptic age. [112]
