NGC 3923 is an elliptical galaxy located in the constellation Hydra. It is located at a distance of about 90 million light years from Earth, which, given its apparent dimensions, means that NGC 3923 is about 155,000 light years across.

NGC 3923是殼層星系的一個例子，它星系暈中的恆星層層排列著。 NGC 3923擁有的層層多達42個，是所有殼層星系中數量最多的 [3]，而且它的殼層比其它的殼層星系要微妙得多。
