Summary

Description 2002 MS4 Hubble 8x upscale.png	English: Kuiper belt object 2002 MS ₄ , imaged by the Hubble Space Telescope on 9 April 2006. This image was created by stacking two Hubble images (J9FS06R5Q and J9FS06R8Q) taken with the high-resolution Advanced Camera for Surveys (ACS). Cosmic ray artifacts were digitally removed from the stacked image. The stacked image was then upscaled 8 times its original resolution with nearest neighbor interpolation to preserve the original pixels.
