Hippo Shaped Near-Earth Asteroid
A small asteroid passed by Earth Saturday (Dec. 22) and according to the folks at NASA, it looks just like the mighty hippo in new radar images. The asteroid, called 2003 SD220, made the closest approach to Earth in more than 400 years and won't be any closer until 2070, NASA officials said. It last flew by Earth on Christmas Eve of 2015.
