Fly-by radar imaging shows tiny asteroid

Astronomers have obtained observations of the smallest asteroid ever characterised in detail – at 2m in diameter. Interestingly, the asteroid, named 2015 TC25, is also one of the brightest near-Earth asteroids ever discovered. This animation shows a time-lapse of how radar images were obtained of the tiny asteroid during its close fly-by. Dec 1, 2016
