A NASA spacecraft nudged a small, harmless asteroid aside in deep space, the agency announced Tuesday in Washington, D.C., shifting the asteroid's orbit in a test mission to save the Earth.

Scientists created this mosaic of asteroid Bennu using imagery collected by NASA's OSIRIS-REx spacecraft. The asteroid spans about 1,600 feet (500 meters) across.

Astronomers are still watching that asteroid that NASA whacked with a spacecraft back in September, in the first-ever test of whether an asteroid could be deliberately pushed off-course.
