Threatening Asteroid a Gravity-defying Ball of Rubble

 

WBIR-TVWBIR-TV featured the research of Ben Rozitis, a postdoctoral researcher, which found that a gravity-defying asteroid that poses one of the largest threats to Earth is actually more like a giant clump of flour. The fact that the rocks and dust are not flying apart means the asteroid is being held together by something more than gravity. The breakthrough observation from Rozitis is the asteroid is holding together due to “cohesive forces.” To see the story, visit WBIR-TV’s website.
