Through the Galactic Registry, you can symbolically dedicate SDSS J21180+4155 in a name, memory, or message of your choosing. Your dedication is filed permanently in our public registry and printed on an archival 12″×18″ cotton-stock certificate, shipped worldwide. This is not an official IAU renaming — only the International Astronomical Union can officially name celestial bodies — but it is a permanent symbolic act tied to a galaxy that demonstrably exists, can be pointed at from any observatory on Earth, and has been imaged by NASA, ESA, or a ground-based telescope.
