Luminosity- is the total amount of energy emitted by a star, galaxy or astronomical object per unit time.
Absolute Magnitude- the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs. One parsec is equal too 3.26 light years.
Apparent Magnitude- the magnitude of a celestial object as it is actually measured from Earth.
Solar Mass- it is the mass of the sun used as a unit of mass.
Gyr- it is an abbreviation for gigayear (i.e 109 years or a billion years)

Age and Stellar Evolution Stage
Evolution Stage: Procyon A is a main sequence star just beginning its evolution off the main sequence and is often designated as belonging to evolutionary class IV-V to indicate its borderline status between dwarf and sub giant stages.
- Eight brightest star in the night sky
- Procyon A is actually a double star consisting of Procyon A and a tiny, white dwarf Procyon B.
- The closet star to Procyon A is Luyten's Star.
