'''UGC 9796''' is a [[Lenticular galaxy|lenticular]] and [[polar-ring galaxy]] in the [[constellation]] [[Boötes]], and about 250 million [[light years]] distant from [[Earth]]. It is an [[Astronomical object|object]] of great scientific interest as there have been very few [[polar ring galaxies]] discovered. UGC 9796 is a very gas-rich environment hosting as much {{val|5e9}} solar masses of neutral hydrogen.<ref name="Cox2006">{{cite journal |last1=Cox |first1=A. L. |last2=Sparke |first2=L.

This object is also known as ''PGC 54461'', ''MCG+07-31-48'', and ''PRC A-06''
