{{Information

Fair use
This image qualifies for fair use in the articles RD1 because:
 * 1) It helps illustrate how little is known about this distant and hard to detect object.
 * 2) Furthermore, the image provides visual identification, something that would be impossible to do purely in a text form.
 * 3) 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.
 * 4) The image has been previously published on the NASA site noted and  is assumed given its nature to also have appeared in relevant academic journals.
 * 5) Display of the image, will not comprise commercial exploitation of the image as the usage is for non-profit, academic purposes. # Additionally academic interest in the image may in fact be encouraged by its use here, given that its subject is not well known.
 * 6) 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).
