"NASA Captures Slow Spin of Asteroid with Planetary Radar"

NASA's Deep Space Network planetary radar has captured detailed images of the asteroid 2008 OS7 during its close approach to Earth, revealing its size, rotation, shape, and surface details. The asteroid, discovered in 2008, is smaller than previously estimated and has an uncommonly slow rotation. While classified as a potentially hazardous asteroid due to its proximity to Earth's orbit, the recent close approach posed no risk. The radar observations will help refine calculations of the asteroid's orbital path and support NASA's efforts to detect and track near-Earth objects for planetary defense.
