Messier 98 or M98 (also designated NGC 4192) is a spiral galaxy in the constellation Coma Berenices. It has an apparent visual magnitude of 10.1 and its angular diameter is 9.5x3.2 arc-minutes. M98 lies at an estimated distance of 60 million light years. The Equinox 2000 coordinates are RA= 12h 13.9m, Dec= +14° 55´ which makes M98 best seen during the spring. The Messier Spring Star Chart shows the position of all Messier objects visible during that season.

The image above shows the uncropped view of galaxies M98 (right) and M99 (left) through the Takahashi E-180 Astrograph (North is up). The bright star 6 Comae Berenices is located about 30 arc-minutes east of M98. A 3x enlargement of this image centered on M98 appears to the right.

This spiral galaxy was discovered by P. Méchain in 1781. It is a member of the Virgo Cluster of galaxies. According to Stoyan et al. (2010), the distance of M98 is 44.2 million light years and its diameter is 126,000 light years. Its estimated mass is 200 billion solar masses.
