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).
