Impending Asteroid Threat: NASA Reveals Multiple Close Calls with Earth

NASA has revealed that a 140-foot asteroid, named Asteroid 2023 TL, will make its closest approach to Earth today, but it is not classified as a Potentially Hazardous Object. Meanwhile, AI algorithms are aiding in the discovery of asteroids, with one algorithm, HelioLinc3D, helping researchers find a potentially hazardous asteroid named 2022 SF289. In another development, astronomers have proposed using an asteroid tethered to a space-based solar radiation management (SRM) shield as a counterweight to mitigate climate change.
