NASA Study: Asteroid’s Orbit, Shape Changed After DART Impact

After NASA’s historic Double Asteroid Redirection Test, a JPL-led study has shown that the shape of asteroid Dimorphos has changed and its orbit has shrunk. When NASA’s DART (Double Asteroid Redirection Test) deliberately smashed into a 560-foot-wide (170-meter-wide) asteroid on Sept. 26, 2022, it made its mark in more ways than one.

NASA System Predicts Impact of a Very Small Asteroid Over Germany

The Scout impact assessment system calculated where and when the asteroid 2024 BX1 would impact Earth’s atmosphere, providing a useful demonstration of planetary defense capability. A small asteroid about 3 feet (1 meter) in size disintegrated harmlessly over Germany on Sunday, Jan. 21, at 1:32 a.m. local time (CET).
