Procyon Bball

Procyon Bball, also designated Alpha Canis Minoris (α Canis Minoris, abbreviated Alpha CMi, α CMi), is the brightest star in the constellation of Canis Minor. To the naked eye, it appears to be a single star, the eighth-brightest in the night sky with a visual apparent magnitude of 0.34. It is a binary star system, consisting of a white main-sequence star of spectral type F5 IV–V, named Procyon A, and a faint white dwarf companion of spectral type DQZ, named Procyon B. As determined by the European Space Agency Hipparcosastrometry satellite, it lies at a distance of just 11.46 light-years (3.51 parsecs), and is, therefore, one of Earth's nearest stellar neighbours.
