I’m not really sure why that needs an explanation. All our imaging technologies have a certain maximum resolution. The asteroid is small and far away, ergo we are not going to get many pixels.
- mturmon 15y agoI agree, about resolution. But, people looking at the image may not understand it is a radar image, not an optical image. People might think that the highlights on the top of the image are sunlight, and the dark area below is shadow, but of course they're not, because radar doesn't care about sunlight. In fact, I'm not sure how they pseudo-colored the images. In vanilla radar imaging, you get the highest return off surfaces that are perpendicular to line of sight (generally speaking). Here's a (model) plane radar image: http://www.fhr.fraunhofer.de/fhr/site/drucken_c336_f4_en.html http://www.fhr.fraunhofer.de/fhr/site/drucken_c336_f4_en.htm... A lot of the radar imaging work is classified.
