List of stars with resolved images

From Wikipedia, the free encyclopedia
Jump to navigation Jump to search

Template:Short description The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun, observed from Earth, stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image. For example, Betelgeuse, the first star other than the Sun to be resolved, has an angular diameter of only 50 milliarcseconds (mas).[1]
