NGC 3608is anelliptical galaxylocated in theconstellation Leo.It was discovered byWilliam Herschelon March 14, 1784.^[4]

NGC 3608 is part of theLeo II Groupof galaxies, includingNGC 3605andNGC 3607.It is approximately 13.0 billion years old. There is diffuseX-rayemission coming from this galaxy and NGC 3607, which suggests that the two may be merging.^[3]

NGC 3608 has a significant population ofglobular clusters.The population distribution is bimodal, with "red" and "blue" populations; the blue globular clusters form a majority. The blue globular clusters have a more extended distribution throughout the galaxy. Overall, the globular clusters are aligned along an axis that is not the same as the rest of the stars, which may be further evidence ofgalaxy interactionwith NGC 3607.^[3]

A large structure of neutralhydrogengas known as anH I region,about 130,000 light-years (40 kpc) across, exists some twelve arcminutes (corresponding to about 230,000 light-years, or 70 kpc) away from NGC 3608. It may be associated with the galaxy.^[5]
