For example:
Below is a radar view of asteroid 2021 DA14 as it receded from the earth after its flyby on Feb.15th.
Radar observations of asteroid 2012 DA14 generated from data obtained by NASA’s Goldstone Solar System Radar on Feb. 15-16, 2013. During the observations, the space rock’s distance increased from 74,000 to 195,000 miles (120,000 to 314,000 km) from Earth.
The movie is comprised of 73 radar “images” looped nine times.
Resolution is 4 meters per pixel.
