                         reduce the volume of many instruments aboard spacecraft, 
                         especially for small spacecraft (cubesats or nanosats) with very 
                         limited mass, volume and power budgets. With the current trend of 
                         miniaturizing spacecraft instruments one could naturally ask if is 
                         there a physical limit to this process for star sensors. This 
                         paper shows that there is a fundamental limit on star sensor 
                         accuracy, which depends on stellar distribution, star sensor 
                         dimensions and exposure time. An estimate of this limit is given 
                         for our location in the galaxy.",
