M100 is considered to be one of the brightest members of the Virgo cluster of galaxies. It's strong spiral structure is though to be heavily influenced by three smaller nearby galaxies shown in this image. Spiral galaxies with prominent arms such as M100 are know as "Grand Design" galaxies.

In 2006, a supernova erupted in M100.

M100 lies at a distance of approximately 60 million light-years.
