YZ Canis Minoris is a red dwarf star in the constellation Canis Minor.[1] It is a flare star, so called due to its solar flares being more powerful than those of Earth's star. It is a Dwarf star roughly three times the size of Jupiter, and is 20 light years from earth.[9] The radiation from the star is in a 50 mHz bandwidth and is centered on 1464.9 mHz.[10]
