Incredible Radar Image of Near Earth Asteroid


NASA have released this image of an asteroid that came to within 1.5 million miles of Earth. The asteroid is 400 metres long and 200 metres wide. It is classed as a ‘contact binary’ because it appears to be two asteroids in contact with each other. The image shows incredible detail of this relatively small space object. The image of asteroid 2006 DP14 was created using Delay-Doppler radar imaging by NASA scientists at the Deep Space Network antenna. 

Radar is useful when it comes to asteroids as it can not only image the size and shape of an object but also surface features and roughness. This allows scientists to be able to improve the accuracy of predicting the asteroid’s orbit in the future to ensure it isn’t on a collision course with us.
