A very nice radar image of asteroid 2017 BQ6.
This composite of 11 images of asteroid 2017 BQ6 was generated with radar data collected using NASA’s Goldstone Solar System Radar in California’s Mojave Desert on Feb. 5, 2017, between 5:24 and 5:52 p.m. PST (8:24 to 8:52 p.m. EST / 1:24 to 1:52 UTC). The images have resolutions as fine as 12 feet (3.75 meters) per pixel. – NASA
This newly discovered asteroid passed 6.57 lunar distances from Earth at 06:35 UTC a couple days after this image was acquired. The asteroid has a diameter of 177 meters / 581 feet and will pass again in 2036 (but not quite as close).
