Revealing the surface of an asteroid using robotic telescopes

...compositions of asteroid surfaces to characterise them individually as well as looking at them as whole populations. Surface properties such as composition, grain size, cratering fraction, etc. affect the way that a surface reflects light. Therefore, we can infer information about these properties from brightness measurements over a range of viewing geometries. By...
