M98 is one of uncountable galaxies in the Virgo Cluster spread out high up in the spring sky, the galaxy lies around western edge of the Cluster. The galaxy can be found about 6 degrees east of Denebola, beta Leonis. Though it has a sufficient length of 10 arc minutes for small scopes, fairly fine object about 10th magnitude. You ought to search the galaxy with telescopes very carefully.
It's considered that M98 is a spiral galaxy and we see it being edge on, and it has fairly complicated structure. The galaxy has an impression of the shrinked M81, very noticeable edge-on galaxy in Ursa Major. M98 is lying around close-side to us in the Virgo Cluster, about 36 million light years away.
