Fair use
This image qualifies for fair use in the articles 52975 Cyllarus because:
 * 1) It helps illustrate how little is known about this distant and hard to detect object.
 * 2) There is no freely available alternative to this unique image since it is not a frequently photographed subject and is beyond the reach of amateur astronomers.
 * 3) Displaying this simple image of a poorly known object on a non-profit website (Wikipedia) should cause no financial loss to the copyright holder(s).
